Antenna for ocean starlink use?

513 Views 17 Replies 7 Participants Last post by  Brandon Davis
Hi. I have done some reading about this and am still a bit unclear regarding the antenna for ocean use with starlink. Does anyone have a concrete answer on this? I am wondering if I can use the standard dish on my boat globally? It would appear the standard dish is not rugged enough to survive the elements on the ocean, but the marine version is quite a bit more expensive. Has anyone permanently mounted their standard dish, and was salt spray etc an issue? What I have gathered so far is that any antenna can work anywhere with the correct plan. Thanks

Yes, you can use the normal dish.

Can i look at this question tomorrow, please?

Several boats in my area have installed starlink in the last several months. The big boats seem to be using the top tier equipment. The sub-60' boats seem to be mostly using the RV rig. So far, after getting the installation glitches worked out, the RV rigs seem to be OK. But none of them have reached the 6 month mark in a salt environment yet, so the jury is still out on longevity.

I was surprised to see a rolly polly little ice breaker hold a usable signal on a day when the sea state was less than friendly. That rig is still working.

As for world wide use, from what I read, it seems to be workable. But I have no personal experience with taking it far from home, so I don't really know. According to friends & boat neighbors, it does work on short trips to neighboring countries. Somebody was telling me that if you move to a different place for too long, there was some issue with billing. I don't remember the details.

Thanks for the responses. I guess my question really comes down to whether or not the more expensive dish is worth the extra, and if the 2 dishes have effectively the same usability. I think I saw someone post about mounting the dish inside the boat which seems like a good option for keeping the salt off of it, assuming you can use the standard dish globally.
I haven't seen an antenna mounted inside yet.

I'd wait to hear what Mark has to say tomorrow. He's a lot more up to speed on this than I am.

Let me barrel through the stuff including the question raised in the other thread

The difficulty with becoming a Starlink Guru seems to be that if you don't have an account with them, then the tech support guys don't want to talk to you at all. Poor lowly marine electricians who don't have the system owner's credentials are left to guess at how the system needs to be installed.

This is not personal experience. These are just the complaints that I hear on the docks.

I'm glad to hear that you are in an area where information is flowing freely. Thank you for sharing.
There is no tech talk needed. Its so absolutely simple that its really making some people very angry. They want it complicated and demand it so ... to the extent they are breaking their devices.

Here are the instructions from the box:
Rectangle Slope Font Schematic Handwriting

That is all you get. That is all you need.

Water Sky Cloud Lake Watercraft

Here is my unit in the pipe of the old wind generator. My pipe is 2 inches Inside Diameter and the Starlink pipe is 1.5 inches Outside Diameter. I wrapped it with rubber sheet and lucky to have the convenient 8 bolted sleeve.

This is the RV antenna. Its aprox $500. The Maine antenna is aprox 5 times the cost at $2,500. I am not buying the expensive one, not now, not ever. If this one breaks I will just buy another RV, now called Mobile, antenna.

The RV is quite low power draw, about 34 watts, sometimes 53 watts when its searching/connecting.
I understand the $2,500 antenna uses more power

Here are the installation mistakes many make:

As its so simple people try to complicate it and have complicated it.
1) They change WiFI router. I don't know why as it supplies info for the app to work. You must have the app to "Stow" and "Unstow" the antenna. If the boat moves at anchor I find it is better to "Stow" the antenna and then "Unstow" it. Then it will move the dish looking directly up, search for the best spot and then turn the antenna to face that spot.
2) People think the RV one works better without the motor. So they break into the dish and unplug the motor. This is insane as the RV antenna does not have the same angle of reception to the horizontal that the expensive antenna has.
3) They try to make it 12 volt instead of the 110/240 volts. They use a POE voltage injector. BUT the units then become scratchy because the voltage is not what they think. I think its like 50 volts(?) but really 55 volts are required. To change the voltage they need to break into the dish and completely pull it apart.

Note: these mistakes all seem to come from the Starlink for Boats Facebook group. I have never read a bigger load of codswallop than in those pages.

How My Starlink Works

It works SIMPLY. It simply works. Simple instruction sheet. Put it together and it works.
I use mine with an inverter. 34 watts up to 53 watts. The draw is really quite low. I often run it 24 hours per day. Sometimes I turn it off at night.

It works well at sea.

After turning the switch to the router on it take a LONG time to boot up. Maybe 10 minutes often. Sometimes only 2 minutes. The 10 minute time feels like forever, so people mistake it for no coverage.

As I said above If the boat moves at anchor I find it is better to "Stow" the antenna and then "Unstow" it. Then it will move the dish looking directly up, search for the best spot and then turn the antenna to face that spot.

If you have a mountain cliff or trees immediately to the north of you blocking out part of the sky Starlink will be slower, have disconnections and is generally grumpy. It prefers looking north. Your area maybe different.

***When putting the cable connection into the dish pole it is very difficult. Its doesnt quite fit. You need to put a shim of paper, say 2 thicknesses, under the plug and gently work the cable in. Ensure it clicks home. Watch this video Starlink Cable Installation Trouble Quick Fix + Speed Test - YouTube

How the plug looks and how to bend it around a corner: Starlink Dish plug how to Mouse It to run through pipe - YouTube

Changes to Plans / Prices / in motion

There was an email sent to every mobile subscriber telling them they had been using their Starlink against TOS and prices are going up, and that Starlink in motion at sea will require and extra payment of about US$2.50 per GB. Plus you need the $200 plan instead of the $130 plan. ***But when you arrive at port you can switch back to the cheaper plan,. Plans by the month, so not pro-rata by day.

No one has been cut off yet. But things are up in the air. The Regions are BS in the Caribbean. I guess the rest of the world is easier to work out.

My advice is, if you do not NEED Starlink now it would be good to wait till they get it sorted out. But they have bigger fish to fry than a few hundred boats.
If you buy it now, budget on $130 while at home. $200 when you want to go to actually be at sea on passage. At sea an extra $2.50 per GB.


Conclusion:

Don't overthink this. Its simple. Its Plug and Play to the max. Run it through the inverter, don't rip it apart. It was designed by experts with a motor in it - It will not work better if you disconnect the motor. Buy the $500 mobile/RV antenna not the $2,500 unless you have money to burn and have the extra power to run it.

In 1 year we will know more about the longevity of the dish, and the Plans. Its so good, its worth it to buy a new dish every few years.

End Point: It is so great you will never regret it!


Any questions?

Mark :)

Mark, sounds complicated. Can you break it down for us simpletons? Just kidding. I guess if you can plug in a lamp you can install Starlink.

I am very interested in hearing from someone that has the $2500 stationary antenna.

For salt water environment, this seems like the way to go- except for the price. Small electric motors exposed to salt will not last long.

I searched the net for a Starlink teardown vid's. They all seem to be interested in the electronics. However, I was able to get a look at the motor assembly. It looks like the motor(s) is fairly protected in a plastic unit that contains the motor and gears and attaches to the antenna housing. Thats better than I expected, although if theres a way, moisture will get in eventually.

How much antenna movement is there? If a boat is swinging on anchor, is the antenna adjusting accordingly?

Thanks Mark, great post!

It doesnt move at all. Then an hour or 2 later it has moved. It just finds a time when you are not looking and moves either to a better position, or, straight upwards to assess the best position.

Thats why I "stow" and "unstow" it sometimes. That forces it to an orientation for its box, so when you unstow it the dish must look for a good spot.

Its not like a normal sat dish that tracks a satellite by moving all the time. It sits in the best position and waits for satellites to go over.

Thank you for the excellent info. Very reassuring. It seems like maybe the saltwater isn't a huge deal. I wonder if I could seal the dish for peace of mind?

I dab of sealant over the plug, maybe. But you need to be able to get the sealant cmopletely off as the plug is hard to get n and a remaining dot of sealant could stuff it.
Around the join of the dish, perhaps?

It doesnt feel totally robust... but then did you see the interior of the SpaceX rocket with the astronauts? It looks like a plastic box with an iPad that a second rate Sci Fi TV show might use.

No one is complaining about it.

@Zanshin may know more about the materials/quality/engineering than me. Lets ring his bell: 🔔🔔🔔

(bell rung)

I think that the engineers did a good job with the double-seals for preventing water and dirt ingress. But the cable after the plug is woefully unprotected; a little rubber or silicon grommet along the cable that plugs into the base of the dishy would have gone a long way in relieving stress on the plug. I think that the engineers were tasked with a land-based antenna connection and not a marine-based (moving) one. I think that a good solution, for those of us who might imbibe a glass of wine on occasion, is to take a cork and drill a cable-diameter sized hole through the middle, then taper the cork to fit the bottom of the dishy base. I happen to have a cork handy for a beta-test. And should I mess up, I'll just have to buy another bottle of wine...

This may be a little misleading. The dish DOES track satellites but the method is different. The antenna is aimed electronically. Once it determines its orientation it will position itself to be able to electronically track (aim at) satellites the most efficiently as they travel across the sky. This is why it never moves once it is set when it is mounted in a fixed position. This also explains why it needs to be "re-oriented" occasionally as the boat orientation changes whether sailing or swinging at anchor.

Do you have issues from heeling?

Not that I have noticed. We have not been in boisterous weather since having it. and we are diplomatically not using it at sea at the moment until they work out if its actually going to be charged for.

I've been reading about this on the Facebook group... it sounds like you can toggle it but if you're even near the water it wants to charge you for the more expensive plan anyway.
