I'm new to the Kapiti area and to TC cable. Having moved into a rental property I connected my Freeview satellite decoder up to what looked like the cable for the Sky dish that I can see on the roof. When it didn't work I checked out two other F-connectors (also unlabelled, of course) on an adjacent wallplate. Nothing works. Now, having realised that one of them could well be a TC cable, I'm not sure if the decoder has been fried or whether the lack of signal is due to other causes. Does anyone know if load or voltage on TC or a regular VHF antenna could damage a sat. decoder?
