Apparently there is either too much wood/fiberglass or, possibly, some type of metal shielding/insulation in the upper part of the cap that is blocking transmission. There are NO trees/things blocking the dish signal and everything is connected correctly.
To test I put the dishy outside and it worked fine. Then I placed the dishy back into the upper cabinet - nada, no signal. Then I put the dishy in the windshield and it did not respond from there either. Maybe I'm just pointed completely the wrong way - once we get up/going I will point the coach in a good direction (using the app) and try it in both places again. It would be very convenient if the Starlink sat would work from the upper section in the fiberglass cap, then I could just leave it there rather than drilling more holes in the roof... I know this would be limited in some areas as trees or other obstacles might block the signal...
Inside the coach is not a good idea in my opinion you're inside a ferrite shield surrounded by metal and thick fiberglass. We put ours on top of the solar panels used in existing hole in the roof for which all the old satellite cables went. Bought the ethernet connection for the dish on Amazon and ran that down to a router inside the bus.
I got a starlink mini recently and leave the large dishy at home now. I was able to use the mini through the front windshield going down the road watching YouTube videos and it worked fine. Once at the campground i put it outside and ran the power cord through the side window but worry it will get stolen - is there any steel in the roof that I can use magnets to hold it on or do the suction cup mounts work?
Every 24 inches is a steel rib that the aluminum is riveted to but the aluminum is .1 inch thick and a magnetic mount will not work well. We use a magnetic mount but the 4 magnets are siliconed to the solar panel, you could do the same on the aluminum roof.
