Jan, did you have Sky or Freesat do you know?
Here is as simple a breakdown as I can make it for you.
Satellite. I use Freesat and just put a new box in last year. However down where you are you will need a MUCH larger dish. No reason why you shouldn't be able to watch UK TV on one of those. Although the box is not cheap and you'd need to get it from the UK.
FireTV is nothing more than a sick you put in the back of your TV And it allows you to access TV, Movies and other stuff (normally for a cost), just like a mobile phone, but from your TV with a separate remote control. Think of it like a 56" mobile phone with a remote control.
The catch with the FireTV is that it will display only local content unless you get a VPN.
A VPN is nothing more than grabbing a bit of the UK internet and putting your home into it. Think of the UK internet like a big bubble and the VPN being a long sausage like tube extending the bubble out to your house. Once you are inside the bubble you are in the UK.
The problem is that Amazon and Netflix and the BBC and ITV and, yes you get the picture, everyone and their dog who gives you your "mobile" services on the TV, try very hard to see where you are. This also means that they know who the VPN providers are and will block them. I went through years of paying up to £17 a month for VPN services which worked 3 months out of 4.
So I have satellite TV
I have a very special VPN which costs me $4 a month and provides all my services and is never blocked
I have a FireTV stick plugged into the TV
Starlink is your own internet. Just like the TV, it is satellite based, it has a dish and it gives you a connection to the internet via SpaceX satellites. No cable off your property, works when your local service is down and it's pretty fast. I use it for when I'm travelling for work. This place is a classic example. Advertised as a "holiday cottage with wifi". In this wonderful nook of England there is virtually Zero mobile phone service and the first thing it said in the book was "our wifi is very poor and often goes off, it is BT who do this and we just have to live with it".
My starlink dish is currently on the roof just outside the Velux.
Key thing with Starlink is that it tells everyone where you are in the world.
So you need a VPN.....They say a picture speaks a thousand words.
