[QUOTE="jimmybhoy, post: 328789, member: 247780"] Hi I have an incoming signal from the TV aerial, which has an amplifier in-line just as it comes into the loft. (We are in a crap reception area) It then goes down to the Sky+ box, the F out comes back up to an 8+1 amp from Wolsey, passing through an 18db attenuator first. Now, signal to rooms is OK, but new purchase of a Plasma has shown the sky signal to be not perfect. I can run a Sat grade cable from the RF out to the plasma and get a great picture. The same cable to the amp gives a poor picture. Disconnect the attenuator.... crap picture. Adjusted the RF channel from 68 to 24 - better, but still not great. Disconnected the incoming Aerial signal from Sk+ box, no difference. Internal cabling from back of Sky+ box goes to a wall plate, then TV quality RF cable to amp. Looking for pointers for troubleshooting..... Is the amp any good? Could this be the problem? It was supplied new about a year ago, when we had a better aerial fitted, but still poor TV reception.... hence the need to concentrate on the Sky signal. My thoughts are to replace the cable from Sky+ box to amp, then if needs be amp. Thanks Jim [/QUOTE]
