[QUOTE="Owlsroost, post: 752660, member: 83973"] Just a thought - a while ago I had a strange reception problem with one of my UHF DVB-T tuners - I could not get good reception on one RF channel (out of 6), but other tuners fed from the same antenna (via a splitter) worked OK. I eventually found that if I put a bandpass filter (or an attenuator) [B]immediately before[/B] the tuner everything was fine.... My theory (wearing my hardware engineer's hat) was that I was having electrical reflection problems in the cable feeding the tuner input, which was causing a dip in the frequency response at the problem frequency, and putting in the filter/attenuator had the effect of isolating (to some degree) the tuner input from the cable. I'm not suggesting that this might be your problem, but since simple bandpass filters or attenuators aren't very expensive it might just be worth a try. Tony [/QUOTE]
