Hi, we have very poor quality programs on channels that are on Mux A, C and D. And are not able to get any HD channels. We have a Sony TV with built-in HD freeview. And channels on other Mux have very well quality. is it because of the band width problem? The arieal is in the attic and the postcode is G72 8AF.
Any advice is appreciated.

Angela: Loft aerials are not recommended for low-power digital as the brickwork and tile reduce the signal level, and hard and metal objects in the loft itself (particularly water tanks) cause reflections.
If it is a Group B aerial, you will struggle to get Multiplex C and D, and the low-power HD multiplex, because they are outside that group. However, don't rush off to change it - all transmissions will be inside Group B after switchover, as are the channels suggested for any new local TV multiplexes that might start up later.
Usually multiplex 2 and A are the first to start going wrong, among the multiplexes that are in-group, if there is a problem with low signal or added interference, because they require more signal than the others at the moment.
If you're getting reasonably clear analogue pictures, you'll probably be fine with the current aerial after switchover. It's only a couple of months away now, so unless you're really desperate for those channels, I'd just wait and see.
If you did have a rooftop aerial fitted, Digital UK's prediction is for completely reliable service. Be wary of installers suggesting tri-boom or X-type aerials, or even Yagi aerials (simple flat rod elements) with more than about 14 elements! You are in a very strong signal area and a high-gain aerial will likely give too much signal after switchover, causing problems rather than solving them.

Hi
Used to receive HD channels on my humax, now nothing being picked up from c59. It says below average does that mean no use...
Will this improve at switchover.
Cheers
Robbo

At the moment the HD service is a low power temporary transmission operating at 10kW. After switchover it will increase to a staggering 100kW so I think you will see a dramatic improvement.

I'm seeing the same as Robbo. I've got a Freeview HD Humax box, and noticed that all the HD channels have gone plus the Mux with Film 4, Dave etc. Everything else is fine. This was fine a week ago, and has been fine for years. Nothing has changed with the aerial.
I was guessing either something was up with the transmitter, or someone has planted a huge tree somewhere between me and Black Hill!

I'm still getting consistent 95% signal strength (100% quality) and I live in the west end of Glasgow - a long way from the transmitter. I have read (and also seen disputed) a suggestion that there is an irregular transmission pattern for this temporary service. I am also using a Humax HD box. As I have said before the power increase and move to the new transmitter may well solve all difficulties so personally I would spend no money (and little thought) on this problem at this stage.
To correct an earlier post, it has been pointed out that to me that increasing power from 10kW is 100 kW is not 'massive'. It does not work that way. It is a 10 dB increase.

Thanks, Mike. I will wait and see after the switchover. Cheers, Angela

Scott: if you get occasional breakup or loss of channels, 10 dB is a great improvement. If everything's solid now, you won't notice a thing. If you already have very high percentages, you could run into problems with too much signal.
The Humax HD boxes are supposed to be properly calibrated this time (the SD boxes aren't), so 95% is safe for now - but it indicates a pretty large signal. Adding 10dB is likely to be too much signal. If you get picture break-up or loss of channels after the switchover, remove any amplifiers or boosters, and if that doesn't fix it, try adding an attenuator.
