I have bought one of these Zinwell STB to receive the new HD Freeview channels. I have connected it all up to an old existing UHF aerial but all I get his the message "No Signal". It might be that the aerial is stuffed. Or perhaps it is the cable from the wall plate to the STB. I read on these forums that "just make sure its solid core cable not stranded". I can I tell which is which? The cable I have is from DSE and is described as "F Type Male to Belling lee Male Flyhead 1.5m". Is this a "starnded" or "solid core" cable. as you can tell, I'm a newbie at this sort of thing, so be gentle :-)
