DJB .I have the same situation with a youview box compared to the tv. I believe that the box is just less sensitive than the tv . Its not surprising really knowing that COM7 and COM8 were around 1/3 power of the other multiplexes . They are now a bit less than 1/5 power. We need a bit more amplification or an aerial having greater sensitivity at the COM7 8 frequencies . Note there is a limit to how powerful an amplifier to use because there is such a thing as too much amplification..

Hrdy and DJB:
In both your cases it could be that you have too much signal, as suggested by StevensOnln1. It is often the case that different equipment responds differently when fed too much signal. So I concur with the suggestion to reduce the signal strengths - it need to be between 60% and 85% for best results.

I agree that if DJB is seeing 100% on com7 or 8 amplification might be too high . In my case on the youview box the level fluctuates between 44% and zero on com8 . Its zero on com7. Its hard to read strength on the tv but the picture is usually fine with no pixelating.

Hardy: I've just been in the loft and placed a 10db attenuator on the distribution side of the amplifier.
On the TV BBC News HD was still available. BBC1 HD and ITV HD had no picture and reported low signal. After a retune they came back and BBC News HD was still there. The TV is being fed from the out line of the Youview box.
I retuned the Youview box and there was no change. BBC News HD still missing. The same 130 channels reported prior to introducing the attenuator.
The final test will be to put the youview box and a TV in the loft and feed it direct from the aerial before the amplifier is involved. I have to do this prior to the soaps starting otherwise I'm dead.

HARDY: This is so frustrating.
In the loft, TV tunes in to everything.
First attempt at the youview box I got Com 8 not Com 7. On the second attempt I got both.
The youview box signal indicator gave a quality reading of about 40 and 20 respectively. The box tuned into 170+ channels. I get 130 downstairs.
Back downstairs and Com 8 and 7 are blank. In addition BBC1 HD etc all reported signal problems. Did a retune and now they are back. Looks like the box locked on to a weaker but viewable mux for BBC1 HD upstairs but that mux is unreachable downstairs.
No problems at all with the channels viewed through the TV.
Youview need to produce a box with a more sensitive tuner.

DJB looking at your post code it looks like you have a difficult situation . ie you are quite close to Sudbury so you should be able to get all its channels reliably with no amplifier . To get com7 and 8 you need to tune to Tacolneston but that will require an amplifier . There is also the possibility of some small signal from crystal palace ,Dover and a local relay!! In such a situation I think a careful choice of aerial (or even aerials !) and type of amplifier would need to be made . It could be that a wideband amplifier like you have cant cope with such a mixture of strong and weak signals . I think the ideal set up would be a non- amplified aerial pointed at Sudbury combined with an amplified aerial pointed at Tacolneston. But the amplifier should be a tuned type only covering UHF 50 to 58. (a relatively expensive set up) The Youview box maybe having trouble with the mixed signals not just a lack of sensitivity . My set up is almost identical to yours but in this location its just weak signal and continental interference that is the problem so I have gone for Freesat .

Hardy: I'm going to have to admit defeat on this one. I only went down the amplifier route as I had missed an episode of Homeland a few months ago and I wanted to watch the replay in HD on C4/7. I had hoped the retune last week would have brought those channels in for me. Ho hum.

The fact you got all channels in the loft suggests that a better amplifier would solve the problem. A wide band adjustable gain one should be ok. Otherwise if youre giving up on com7/8 I would turn the aerial to pick up Sudbury to get all the main multiplexes probably without needing any amplifier.

paul: Some multiplexes changed frequency at Tacolneston last week. PSB1 is now found on UHF channel 40.
