I bought this specific indoor antenna for TCL 65C805 television.

In the Artemida area, about 10Km from the airport, it picks up all the channels. It does pick up ERT channels and Star, but I had to place the antenna in a high spot as far away from other cables as possible.

It's not like someone can just put the antenna behind the TV without it being visible and it picks up everything perfectly. If the area is relatively difficult, you should consider it.

It has a switch to adjust the signal strength, but only adjusting the strength doesn't say much, it needs to have good signal quality as well.

The power and antenna cables are relatively close. It is good to also get an antenna extension.
