Can any of you knowledgeable folks help please ... I have a Panasonic TUCT30 freeview box connected to a loft aerial (not ideal, I know, but we're not allowed a roof one). Signal quality is 10/10 for BBC channels, but varies every few seconds between 4 and 7ish for ITV/C4 (I understand that these are on a different MUX). The result is a freezing picture and spitting-broken-up sound. I'm trying to work out what to change to improve things. Proper satellite cable from the aerial to the box with no joins/connections is recommended, but would this help with these symptoms ? The existing cable seems reasonable quality, although it does go into a box on the wall. Anyone got any other suggestions ? Many thanks in advance, Simon.
