Installing Starlink in an RV / Overlanding Truck

No ‘installation’ is necessary with Starlink. You could of course just get it out of the box and run loose wires from the router and the power-supply (inside) to Dishy (outside) whenever you want to use it. However, I decided to instal the system more permanently into our Cuthbert so as to:

avoid having to open a window/door/mosquito net to accommodate the cable running outside to Dishy;
tidy-up loose cabling; and
simplify/speed-up the set-up/pack-up of the Starlink system.

With this installation, all I have to do to setup the Starlink connection is put Dishy on his tripod outside (or Volcano mount on the roof – see above) and plug in Dishy’s data cable to a plug on the roof or in a lower locker. Inside Cuthbert, I simply switch on the inverter and the power switch for Starlink.

Installing Dishy’s power-supply

I mounted the power-supply on the wall in the electrical equipment cabinet inside Cuthbert. For a bespoke fit, I designed a bracket of exactly the right size and was lucky enough to have a friend produce my design on his 3D printer. The two brackets hold the power-supply at each end and spaces it 5 mm from the wall. This allows ventilation around the power-supply for cooling. Obviously having the bespoke mounting bracket is an unnecessary little feature that I have added (just because I could 😉) but wherever you decide to house it, take care to allow some room around it to allow for the cooling. To help with the cooling, I have also added a few stick-on heat sinks onto the power-supply. The mains power cable is wired to the inverter through a power switch which is accessible outside the cabinet.

Installing the Router

I also mounted the router on the wall in the truck’s electrical equipment cabinet alongside the power-supply (as with the power-supply, this is mounted with bespoke brackets that I designed and had produced by a friend on his 3D printer, but it’s obviously not necessary to have this). I have mounted the router up-side-down so that the reset button is easily accessible. I have added a panel mounted RJ45 socket that attaches to the AUX port of the router. This allows me to easily plug in my computer without accessing the cabinet where the router is installed. I have also attached a plastic optical fibre over the router LED and installed it through the side of the panel mounted RJ45 socket moulding so the LED can be monitored without opening the cabinet.

Installing the Volcano Mount

I have installed the Volcano mount in a position on the roof that is easily accessible from inside the truck by the roof-hatch. Dishy is not designed for high wind-speeds (from the Regulatory Notices²: ’Mounts are not designed for hurricane/tornado wind loads’) and so presumably it would also not cope well with the dynamic loads experienced while braking. It should therefore be taken down from the Volcano mount and safely stowed away before driving.

The Regulatory Notices also say that ’During normal operation to avoid possibility of exceeding the FCC/Industry Canada radio frequency exposure limits, this equipment should be installed and operated with minimum distance of 28 cm (11 inches) between the radiator and your body’ so the roof-top is a good option for us as the dish is more than 28 cm (11 inches) above the volcano mount when in operation.

Dishy installed in the Volcano mount on the roof.

Installing Data/Power Sockets

As noted above, when Dishy is set-up outside either on the tripod or on the roof-top Volcano mount, you can simply connect Dishy to the power-supply and router mounted inside the truck, by running a loose cable outside from Dishy. However, to avoid having to open a window/door/mosquito net to accommodate the loose cable, I installed fixed external waterproof sockets: one socket on the roof next to the Volcano mount, and another at ground level (in an external locker). With these, Dishy can be quickly/easily ‘plugged in’ when we arrive at our camp spot.

First, I needed extension cables for the PoE data cable between the power-supply and the external sockets. The Regulatory Notices say: ’To maintain compliance with FCC Rules and Regulations, connections to this device must be made with shieled cables have metallic RFI/EMI connector hoods.’ I have therefore used good quality screened Cat 8 ethernet cables. Given the high power of the PoE, I decided to use data cables of at least 24 awg to minimise any voltage drop. I believe others have found 24 awg to be okay for up to an additional 50’/15 m. If you extend Dishy’s PoE data cable by more than 50’/15 m, you will need a larger 23 awg (or bigger) cable to reduce the voltage drop, otherwise Dishy will stop working.

Waterproof cover fitted to Dishy cable plug and the waterproof socket

Dishy plugged into our lower equiment locker waterproof socket.

Roof mounted waterproof connector with aluminium cover plate over the waterproof box for extra protection.

Once the external sockets and their extension cables are in place, the ‘easy’ way to connect Dishy is to simply plug the relevant extension cable (i.e. the extension from either the roof socket or the ground level socket, whichever is being used) into the power-supply by plug. However, I have seen reported that constant plugging/unplugging into the power-supply can lead to poor connectivity with plug pins breaking. I therefore wanted both external sockets to be connected to the power-supply at once. This would allow me to plug Dishy into either of the external sockets and no wiring would need to be changed or switched over at the power-supply.

Unfortunately, I could not find a commercially available device for joining two RJ45 plugs of the PoE data cables into one (without reversing the data lines or that could handle the power) so I designed and made my own. For those of an even more geeky disposition who want to make their own, read on below in the ‘Top-geekery Bonus Installation Section‘: Jointly connecting both external sockets to the power supply…

Jointly connecting both external sockets to the power-supply

With this installation, Dishy can be plugged into either of the external sockets and no wiring needs to be changed or switched over at the power-supply. Unfortunately, I could not find a commercially available device for joining two RJ45 plugs of the data cables into one (without reversing the data lines or that could handle the power) so I designed and made my own. I chose 1.5 mm wide PCB tracks to easily handle the power. Obviously nothing else should be plugged into the unused socket.

See Update No. 2, we are no longer using this connector

Here is my design of the circuit and PCB in Eagle:

The PCB design using 1.5 mm wide tracks.

The waterproof plug, socket and the PCB RJ45 socket that I found are only rated to 1.5 amps and not the 1.6 amps of the power-supply. The 1.5 amps rating would provide a maximum power of (1.5A x 56V = 84W x 2) 168 Watts, which is more than the peak power of 159 Watts I have observed to date. Therefore, I am happy that the 1.5 amps rating will be fine.

Dishy has some large ferrite cores on its data cable, presumably to reduce RF noise from Dishy. I have added similar but smaller ferrite cores at both ends of the patch cords that I have added between the waterproof sockets and the power-supply and one in the middle of the patch cord from my PCB to the power-supply The PCB is fixed inside the cabinet near the power-supply.

Geek Info – System/Equipment Data and Specs

Okay… you really don’t need to know this stuff. But here’s a bit more tech detail:

The Starlink Constellation

As mentioned above, Starlink by SpaceX is a constellation of low-earth orbit satellites (approx 550km above the earth – much lower than a geo-stationary satellite) with the advantage of a low-latency satellite connection. The constellation is designed to use 12,000 satellites and SpaceX has developed an ‘affordable’ launch system that will see the deployment rate increase rapidly over the coming months.

Starlink orbit compared to geostaionary to scale.

Once they’re all launched, the satellites are going to be arranged in several overlapping ‘shells’. SpaceX’s latest plan is for an initial deployment of 4 shells, the first of which will contain 1,584 satellites at an orbital inclination of 53.2 degrees (the satellites will travel north and south of the equator to a latitude of 53.2 degrees). They also plan on shells with orbital inclinations of 70 degrees and 97.6 degrees to provide global cover by the end of summer 2021. Additional shells will be added over these to increase the capacity of the network as more users come online. As at 7 April 2021, SpaceX already have 1,378 operational satellites in the first shell, ten in the 97.6 degree shell which are providing the ‘beta service’ for internet.

Note: all equipment dimensions noted below were measured in mm and converted to inches

Mast diameter 1.4”, 35.6 mm (the section that plugs into the mountings)
Dishy weight 12 lbs, 5.4 kg
Cable weight 3.5 lbs, 1.6 kg (cable is not detachable from Dishy end)
Cable length 100’, 30m
Ferrite cores:
- Dishy end, 0.9” 22.8 mm diameter 2.3” 59 mm long
- Plug end, 0.8” 19.5 mm diameter, 2.2” 55 mm long
Cable 0.3” 6.9 mm diameter

Normally when a satellite dish is set up, it needs to point extremely accurately. Moving a satellite dish by just one degree will move the beam by 642 km at a geostationary satellite! Dishy however, is using low-earth orbit satellites, so one degree of movement only moves the beam by 9.6 km at the height of the satellite.

But of course, it’s not quite as simple as that. Geostationary satellites are – as their name implies – stationary (well, they’re orbiting at a speed of 11,052 kph, so as the earth rotates, they appear stationary to us on earth). Low-earth orbit satellites are moving at approximately 27,720 kph, so Dishy needs to track the satellites as they fly overhead. By my calculations the longest a Starlink satellite will be visable to Dishy is only 110 seconds! Luckily, Dishy is not like your every-day, conventional satellite dish. Dishy is a phase array!

My calculation of overflight time for a Starlink satellite.

A phase array antenna is a very clever device. Rather than using one transmitter and receiver, it uses a lot of transmitters and receivers that can be controlled individually. In the case of Dishy, it has about 1,444 individual transmit/receive cells spaced half a wavelength (transmission frequency) apart.

λ = v / f

v = speed of radio wave in air = 299,792,458 m/s

f = Tx frequency = 14.25 GHz

λ = Tx wavelength = 0.021 m = 21 mm

Half wavelength spacing = 10.5 mm

If you imagine having two transmitters next to each other spaced half a wavelength apart and they both transmit at the same time the signal from the two transmitters will cancel each other out to the sides (due to the half wavelength spacing between them) and the signals will combine straight ahead. If you now multiply this across a large array you can get a very directional pencil beam. Now rather than transmitting at the same time, you change the transmission time slightly between adjacent cells. The way the transmission waves interfere with each other will change slightly. This will tend to cause the resultant beam to move towards the side that transmitted last. In school during a physics lesson you may have seen this effect when you dropped a small stone into water and saw the ripples on the surface, then dropped two stones into the water and saw the interferance pattern between the ripples.

Dishy does not transmit pulses, it transmitts a continuous wave, so to achieve the same effect as delaying transmission time between pulses it changes the phase of the transmission between adjacent cells to create the beam steering effect (this is a simplification, but hopefully the analogy above helps you visualise what is going on). This change in phase changes the direction that Dishy transmits and can be controlled in both azimuth and elevation. The same principle can be applied to the receivers which allows dishy to ‘listen’ in specific directions too. This is called ‘electronic beam steering’ and means that Dishy does not need to physically move. Without moving, Dishy can see ±50 degrees off the centreline of its face, in both azimuth and elevation. It also means that Dishy’s beam can be steered almost instantaneously from one side to the other, something a conventional dish could never achieve.

With a ±50-degree beam capability, Dishy can see a 100-degree wide cone of the sky. That’s wide, but unfortunately not quite wide enough. During the initial roll-out of Starlink, satellites may need to be used that are only 25 degrees above the horizon (as the constellation grows, satellites less than 40 degrees above the horizon will not need to be used), but Dishy has a solution to this. When Dishy is powered up, the first thing it does is point straight up. It has a couple of small electric motors within the antenna so it can adjust the dish’s position. Dishy is clever and has some level sensing devices (just like in your phone). This means that when Dishy is set up, its mast only needs to be within 40 degrees of vertical. The on-board sensor will automatically find level and point the dish straight up. This is perfect for a quick setup at a camp-spot or if you put it on the roof of your rig it does not matter if you are not parked level.

Once it is level, Dishy will get a GPS fix and scan the sky to listen for Starlink satellites. Once it has worked out its position and where the nearest Starlink satellites are transiting past, it will turn and tilt to optimise itself for electronic beam steering. Once in this position, it will not move again until you tell it to ‘stow’ in the App when you come to pack it up. In the northern hemisphere, Dishy will generally tilt to the north and in the southern hemisphere to the south. This is to optimise reception and partly to avoid the dish from pointing towards any geostationary satellites that could be affected by the Starlink as it shares some of the same frequencies (Tx 14 GHz to 14.5 GHz and Rx 10.7 GHz to 12.7 GHz). See update #8 on Starlink Mobile Roaming for latest information.

Power-Supply – Data and Specs

Height 1.4” 35 mm x length 6.3” 160 mm x width 3.4” 87 mm at bottom, 23” 75 mm at top
Weight 1.1 lbs 0.5 kg
Input, 100 to 240 VAC ~ 2.5 A 50 to 60 Hz

PoE output 1b, 56 VDC 1.6 A (89.6 W)
PoE output 2, 56 VDC 0.3 A (16.8 W)
Total maximum output 180 W

The power-supply is of a switch mode type. Just like many laptop computer power supplies, it can accept an input of 100V to 240V AC, 50 Hz to 60 Hz. It provides Power Over Ethernet (PoE) through the data cables to Dishy and the router. The power supplies maximum output to the router (white port) is 56V DC at 0.3 amps and to Dishy (black port) two feeds of 56 V DC at 1.6 amp each.

The maximum power of the power-supply is 180 watts, but from my observations the average power draw is about 99 watts with power fluctuating between about 87 watts and 159 watts (the coldest we have tested to is -5C (23F), in colder conditions the peak power may be higher). The PoE output to the router will detect if a non PoE router is attached and will not turn on PoE if it is not required. This means that non-Starlink routers or your computer can safely be attached. Comments on Reddit have reported that the power-supply will not work on non ‘pure sine wave’ inverters.

Operating the power supply mounted in my designed 3D printed brackets from our 230V pure sine wave inverter with the stick-on heat sinks has produced a maximum temperture of 46.7C (116F), but we have not operated it below -5C (23F) in snowy conditions where it may use more power to clear the snow.

Weight 0.9 lbs 0.4 kg
PoE input 56 VDC 0.18 A

The router is PoE through the data cable and provides 2.4 GHz and 5 GHz Wi-Fi. There is also an Aux port to attach a computer directly. The administrator side of the router is not accessible . Many people seem to have used their own routers, rather than the one provided by Starlink. There are a few technical issues with doing this, but there are work-arounds if you understand routers. Some have reported faster speeds using the Starlink router rather than a third party router, others the opposite, but the Starlink router is more than adequate for our use and being PoE does not require another power supply. Connecting to the AUX port could provide higher data rates then connecting through Wi-Fi.

Update No. 1: 7 May 2021

To store Dishy while not in use and while driving we now attach it to the underside of our table. This location is quick and easy to access and does not get in our way whilst sitting at the table. To protect Dishy’s face we have glued some felt fabric to the underside of the table. Dishy is then held in place with a three-legged strap system.

Felt protection glued on underside of table and three legged strap.

Plenty of leg room even with Dishy stored under the table

I have also cut down the dish cable by approximately 95’ (29m) as the full length is not required when Dishy is being used on the roof. As a bonus, the average power consumption appears to have reduced by approximately 5.5W to 94.5W. I added two clip-on ferrite cores to the shortened cable to effectively replace the one on the original cable section that has now been removed. I have also added a waterproof socket on the end of the long cut off cable so that it can be used as an extension cable should we want to use the tripod and mount Dishy away from the vehicle.

The cut off cable turned into an extension lead

The dish cable colour coding appears to follow the RJ45 Ethernet cable T-568B straight through standard as follows:

Pin 1 = white with orange stripe
Pin 2 = orange
Pin 3 = white with green stripe
Pin 4 = blue
Pin 5 = white with blue stripe
Pin 6 = green
Pin 7 = white with brown stripe
Pin 8 = brown

Note: In the Starlink specifications (see here) they now list the ethernet cable pinout for the rectangular dish. It is the same colour coding as the round dish ethernet cable.

Update No. 2: 19 September 2021

SpaceX’s software updates have been improving the service, resulting in two significate effects on our installation:

1. The dish has become more sensitive to ‘slow ethernet connection’, so I have had to remove the ethernet junction I had made. It had originally worked well with early software versions, but now I simply switch the cable from the roof or lower socket to the power supply as required. This isn’t an issue for us as most of the time we use the roof cable.

2. There has been a significant reduction in power consumption with dish software “f9ff8ff1-b950-4524-8515-a105a2709cc4.uterm.release” that we received on the 26^th of August 21. We are seeing a 20-watt reduction to an average power of 75 watts – this is a significant improvement for us.

Update No. 3: Modifying the Starlink Power Supply to run on AC and DC

Living off-grid, or like us in a motorhome, power consumption can be critical. Having to convert our battery DC power into AC through an inverter, then back to DC through a power supply is not the most efficient way to power any device. We love having Starlink in our overlanding truck, but the power consumption can be a bit of a concern sometimes. So I wondered… would a DC power supply save a few valuable watts that are normally lost through the DC to AC to DC process? Click here for more information.

Update No. 4: Starlink Mobile Roaming

Now that roaming has been enabled on our Starlink, I have changed our installation to make the most of roaming. See: Starlink Mobile Roaming

Click here for our other Starlink pages.

Update No. 5: Rectangular Dish

Unfortunately, we were not allowed to update our registered address to Mexico from the USA. We have therefore sold our round dish to an American family and purchased a new rectangular dish for Mexico. With the circular dish we have liked having it mounted flat on the roof of the truck (in the spare tyre, see more here) as it saves us having to set-up and take-down the dish when we want to drive. So this is how we installed the rectangular dish on Cuthbert.

I cut a hole in the back of the dish so that I could install a switch to disable the motors. This will allow the dish to be flat mounted like we did with our round dish. I followed Pat Chicas’ directions for hole location (see more here). The two motors are wired into a single plug. The black and white wires go to one motor and the red and blue wires to the other motor. I cut the white and blue wires, extended them, and connected them to a double pole switch.

To make the installation as easy as possible, I am reusing the existing Starlink wiring in the truck. I cut the cable about a meter from the dish and installed a waterproof shielded RJ45 connector wired to T-568B standard (see round dish installation details above). This connector can be plugged into the existing Starlink cabling that I installed for our round dish. Note: Wiring to T-568B standard allowed me to power the Rectangular Dish using the power supply from my Round Dish!.

At the router end, I also cut the cable and installed a shielded RJ45 connector wired to T-568B standard. This is joined with the existing Starlink cable from our round dish installation, using a shielded ethernet joiner.

I also modified the router to run on DC, see here. While modifying the router for DC operation I also drilled three holes in its case so it could be screwed to the wall of the electrical cabinet.

Like the round dish was, the new dish is mounted inside our spare tyre on the roof. It’ obviously not quite such a perfect fit, but the tyre cover goes over the top of the dish to give it some protection from low tree branches and to make it less visible. The tyre cover has not had a significant effect on performance. The operating temperature under the cover has not triggered any thermal throttling issues either.

You may also be interested in my Starlink POE Injector design, see here.

Update No. 6 – Cable Retention Collar

With the dish mounted flat and not using a stand or mounting, there is nothing to stop the plug in the bottom of the dish mast from coming loose. I have therefore made a small plastic collar that clips onto the end of the dish mast. This holds the plug firmly in place.

I used a plastic water pipe joint with an internal diameter close to the required 34 mm. It did take a little filing to make it a good sliding fit on the dish mast. I made a small cut out on one side for the latch on the dish mast to engage in. The plug is now held firmly in position and the cable can be routed out the side or bottom of the dish mast.

Update No.7 – Tp-link Archer AX50 (AX3000) Router Installation

The Starlink router is okay, but that’s about all that can be said about it. There are very few controls and options to set up the WiFi. We have also been a little disappointed with its range outside the truck. So I decided to try a 3^rd party router and chose the Archer AX50 (AX3000).

Connecting the router

With the round dish there are two options:

a) simply connect a 3^rd party router WAN port to the power supply white socket, and use it in place of the Starlink router; or

b) connect the 3^rd party router WAN port to the AUX port of the Starlink router. The problem with this option is that you then have two routers running and 2 sets of WiFi. This is not ideal and is a waste of power, but it’s how we used to provide a guest Wifi using a small Alpha Campro R36 router.

With the newer rectangular dish, you need to buy an ethernet adapter. Then you can connect the 3^rd party router WAN port, and put the Starlink router into by-pass mode (which effectively turns off the Starlink WiFi).

I have put together a ‘pick-and-mix’ system partly from my old round dish, and partly from my new rectangular dish. I used the round dish power supply which I had converted to run on DC. By installing a shielded RJ45 connector (wired to T-568B colour code, see here) on the cable coming from the rectangular dish, it can be plugged into the round dish power supply. I have seen that others have done this and operated the rectangular dish at the round dish voltage of 56V. However, as my system is adjustable, I have lowered the power supply’s voltage to 48V, which is the standard voltage of the rectangular dish.

WAN Internet Settings

For a 3^rd party router to work with Starlink, its WAN Internet settings need to be set to ‘Dynamic IP’. To use the Starlink app or a web browser to view the Starlink Statistics, you need to set a ‘static route’ in the 3^rd party router. For our Archer AX50 router, this is done in the Advanced Network setting. These are the required settings:

Network destination: 192.168.100.0

Subnet Mask: 255.255.255.0

Gateway: 192.168.100.1

Interface: WAN

Static Routing — Static routing setting for the Starlink statistics

Snag solving

One issue I encountered with the Archer AX50 router was it frequently dropping the internet connection. A bit of searching on-line showed this to be a known issue that some routers have with Starlink – it’s to do with Starlink having short breaks in connection and losing DHCP addressing.

I found an article here: https://community.tp-link.com/en/home/forum/topic/563220

The article doesn’t specifically cover the Archer AX50 router, but I tried setting the ‘Internet Port Negotiation Speed Setting’ to ‘100 Mbps Full Duplex’. This didn’t fully solve the issue, so I found the solution was to install a small, cheap, switch between the Starlink and the router.

Advantages and Disadvantage of the 3^rd Party Router

Now fully installed, the new Archer AX50 router advantages for us are:

a true guest WiFi that can be switched on/off (so we can share our Starlink with other campers in remote locations);
a USB port for connecting external hard drives for backing-up data accessible over the WiFi;
a much greater range Wifi (we can now get WiFi over 450m/1476’ from Cuthbert – no more loss of signal if we want to sit outside away from the truck).

Archer AX50 router disadvantage for us is:

higher power consumption, increase of 8W.

We can easily switch between the Archer AX50 and Starlink router. So, in areas where we could be critical on power, we can switch back to the Starlink router to save some power.

Update No. 8 – Dish RJ45 socket modification

The weak link with the rectangular dish is the connector in the mast of the dish. The connector easily becomes loose, even when installed in the stand, which eventually leads to the electrical failure of the connection. We had very strange behaviour from the router: it was disconnecting devices from the WiFi and we were unable to connect again. At first I thought this was a router failure and so connected the dish to a 3^rd party router via a POE injector. Using the 3^rd party router, I discovered that the dish was intermittently disconnecting. I checked the dish connector and it was not firmly into position. After firmly reconnecting the dish cable, I reconnected the Starlink router and it functioned correctly again. Quite why a disconnecting dish would effect the router in this way is bit of a mystery, I would have expected it to just show the dish as disconnected.

This for me was the last straw! I decided it was time to delete the Starlink proprietary plug and socket. So I checked what Oleg had to say…

Oleg has been repairing battle-damaged Starlink terminals in Ukraine and has a lot of experience modifying them too. He has done a great video showing how to install a waterproof RJ45 on the back of the dish. See: https://youtu.be/GKYMd9tDlew

The only change I made to his technique was to drill a hole in the mast insert, so that I could attach a cord.

Hole drilled through the mast insert and string attached to pull out insert after it has been pushed fully in

This allowed me to push the insert further into the mast, so I had a longer length of cable to work with, then pull it out again using the cord. After cutting the cable, I fully removed the insert and then removed the socket from it before reinserting the insert.

The shielded RJ45 plug is wired to T-568B colour code (as are all my Starlink cables).

Pin 1 = white with orange stripe
