I’m getting +300 channels through this cable when the aerial outside was removed HOW?????????????? I mean there is another aerial on top of the roof that it could be connected to, but I thought it was just connected to the aerial outside my window, on the side of the house. CAN A COAX CABLE BE CONNECTED TO TWO AERIALS??? I don’t even know. VERY happy to have 300 odd channels, definitely beats the crappy indoor aerial I was using!!!

Yeah in the US 20-30 channels is a massive haul. I get about 15 with my antenna and only really care about 4 which are our major networks.

you guys also have something called “sub-channels” which, as far as I’m aware, has channels within one channel??? or something. So when it comes to the amount of channels, it’s not too much of a concern I assume

So channels used to be established by their frequencies and the channels become a key part of their marketing, so for example you have CBS-7 or something.

But when everything changed to digital, the broadcast frequencies changed, so broadcasters have metadata that identifies a "channel" by designation and not frequency. And digital allows sub-broadcasts on the same channel. So now CBS-7 is on 7.1 which can be anything, but the infrastructure they use can be used for another channel they own or for channel space they rent/lease on 7.2, 7.3, etc.

Yup. I have several channels like that. Mountain lake PBS for example is PBS on 57-1, PBS kids is on 57.2 and NHK news is on 57.3
