Coach: Channel 4HD is broadcast by the PSB3 multiplex, as are channels (45) Film+1 / 101 to 105 / (123) CBBC HD, are these channels also being affected?

I've noticed a drop in signal power over the last few weeks. All MUXs which used to be about 70/80 power are now down at about 25. The quality is still at 100 and have no problem with the channels but the real issue is that MUX channel 32 which includes BBC4 is now at zero and won't pick up.
Postcode CB22 5DT External aerial on roof/chimney breast. Booster/splitter in loft then leading to a Humax in the living room.
External ground view of aerial seems to be fine. The only idea I have is that we have had some wood fires recently, would this cause an issue with tar coating?
Any other ideas?

Waspattack:
I've lost that multiplex a couple of times recently. Either a fault, or Co-channel interference.

Bob,
Now fixed. Turns out it was the fires/tar that had been causing the problem. The aerial was installed right over the chimney pot and the heat/smoke had damaged the internals. New aerial positioned in a much more sensible position and I'm back to good strength again.

How long has your signal drop on COM7 been happening?
I lost it completely after engineering works at the end of Nov 2015 (see Happy 2016 - welcome to the Golden Age?
I'm at SG4 7SN with a roof aerial and booster(s). COM8 comes through loud and clear, but not COM7.

After a couple of months of good reception on HD channels, this week I'm yet again getting picture break up. Sandy Heath transmitter is stated as having possible weak signal. I wish they were more specifc. Surely they know if it's weak or not.

coach: Not necessarily, as engineers working on RF and associated equipment could well experience some unforeseen problem which could place either themselves, or the equipment they are working on, in danger without a power reduction being made, this being the reason for "possible" weak signal having been posted, as it covers all eventualities.
