David: Have you noticed any degradation at all in the signal/quality for the main HD channels (BBC B mux) - BBC, ITV etc? This is on C58 from Mendip.
Sky News etc is on the Arq A (Com5) mux on C56. If you are also seeing some degradation of those HD channels, then I'd start suspecting some issues with damp/water in the aerial connections or the coax which will start affecting the higher frequency channels first.

Thanks Chris, all HD channels have strong signal. MikeP, I have some signal attenuators which I'll try again. Thankyou.

David, there is an outside chance you are seeing co-channel interference from the Huntshaw Cross transmitter, which reuses UHF channels 52 and 56, the ones you are having problems with. The transmitter is more or less behind Mendip from your location though much more distant. You may be able to confirm this by getting your equipment into a portable state and testing it from a location where Huntshaw Cross is not in the frame to see if it behaves the same. Neighbours are likely to be suffering the same issue.

Used to get Dave and Challenge (Freeview 12 and 46) very well until recently. No signal the last few days. Post code TA24 near Williton .
Not a techie, so any ideas please and anyone else experiencing this? Only the last 10 days or less. Before, it was very good.

I'm in Sturminster Newton and our reception on Freeview has been difficult (not available or breaking up both TV and radio) but it's usual with this weather.

GEM: We need a postcode to know what your signal should normally be like, but weather shouldn't normally be a factor in the breakup of your TV signal.

GEM: As I mentioned in my post replying to Nick Anderson, high atmospheric pressure can indeed affect digital terrestrial television (DTT OR 'Freeview') television reception and if everything such as your aerial (type & condition), aerial alignment, aerial cable (type and length) and connectors have all been checked, and you have also carried out a 'first time installation' retune recently, then you have done all you can, and you simply have to wait until the weather changes and you have low atmospheric pressure again. If you are using the Mendip transmitter, make sure you are using a group E or a wideband aerial, horizontally polarised.Also check whether there are many 4G phone masts close to your location. If there are you may need a 4G filter. You can get them free via the at800 website. Hope the info I've provided here will help you. Richard, Norwich, 2nd June 2016.

Martin B: Hi Martin B. There are no faults or engineering work taking place at the Mendip transmitter at the moment and CITV is currently transmitting, "The Dawn of Morphos (Part 2), which looks very exciting! You could watch it live on the itv hub instead of getting it from Freeview. Your Freeview reception may be marred due to high atmospheric pressure, which is dominant across southern UK at present! Hope this helps, Richard, Norwich, 11:05 on Thursday 2nd June 2016.
