Amazing, thanks everyone for all the ideas, and really useful info.

I think I will try Starlink and the 4G /5G option again. I have a professional Starlink install and an external 4G/5G antenna, but I can’t remember if I tried the Vodafone network. A sim should arrive today. And mr Musk unfortunately is going to get some of my money again.

I think you really want to avoid musk.net ........ Don't blame ya. What antenna have you got and router? We are asking that because it matters ALOT.

As someone else mentioned you need to have the 4G/5G router very close to the antenna. If you have a very long (being more than a couple of metres max) of cable between the antenna and the router then you will get really bad signal loss from that.
