TV in a room with no aerial socket.

[Aquamarine]

Unless you have a strong digital terrestrial signal I wouldn’t faff about with indoor aerials. Get a tv aerial company in to either give you a yargi aerial on the roof or a freesat dish and box. They are never as dear as you think they will be and it’s not a faff for them as they do it all the time.

I suspect an indoor aerial is not going to do anything and will look at what the tv aerial companies offer. Although my place is only 4 miles from the Crystal Palace transmitter, the main station for London apparently, it's unusual for properties around here not to have a roof top aerial or other fixture. When I was living closer to Crystal Palace I had all the Freeview channels crystal clear!
