Indoor aerials are never very reliable. I suggest having an expeternal wideband aerial fitted with suitable attenuation to limit the signal strength to below 85%. It should be aimed to avoid the worst of the possibl intereference from your local mobile masts.

Just a few years ago a respected aerials website suggested that Crystal Palace needed a 'Band A' aerial for optimum Freeview reception. However I can find no current reference to such advice; instead, only that a 'Wideband' aerial is now recommended. So when did the change actually occur and why? In a rather fringe area I had installed a 'Band A' aerial which, with a masthead aerial, still "sort-of" works. Anyone out there know about this, please?

The change happened before June 2018 and was widely reported in the media in that area. Up until the change, a Group A aerial was correct. As COM 7 and COM 8 are now on channels 55 and 56 respectively, a Group A aerial will not give satisfactory reception of those, so a wideband aerial is now required. A Group A aerial is fine for channels 21 to 35 but not above that.
If you go to Digital UK - Coverage checker and put in your full post code and house number, you will be shown the current arrangements as well as the future plans for further changes. If you have a wideband aerial fitted now it will be suitabkle for all changes foreseen in the future.

Can anybody tell me if the BBC Red Button service should be available on BBC News HD ( tv channel 107). I have been having reception difficulties since the June change. An aerial engineer fixed it so that I received the service, but not the red button. He told me that it is no longer available for that service (I receive the Red Button on BBC News SD).

Hi All,
My postcode is SE10 9EY and from 1 June we are getting very poor quality reception on our TV if using the external aerial and not getting any HD channels at all. We initially thought it might be a temporary problem due to the weather but the problem has persisted. We have tried using a 4G filter but to no avail. Currently using an indoor aerial which comes with its own set of problems so not too sure what we should be doing apart from having an engineer look at the aerial? We live in a block of 7 flats and initially everybody was having this problem although it now appears the situation may have improved for some of the residents. Should our aerial be set up on the roof to have unrestricted access and could facing a wall create reception issues?
Thanks
Pooja

Pooja: If this is a communal aerial system then you should contact whoever is responsible for maintenance and get them to send someone to investigate.

I'm SW9 8SE but live next to a railway viaduct at roof-height. My signl was perfect with a large Band A yagi mounted in the loft - but with the migration of Muxes 7 & 8 to Ch 55/56 I have problems. Wideband aerials seem to cannot get me a good enough signal at the low frequency and high frequency end of the band to avoid picture breakup and loss of sound spasmodically when trains pass.
What I also wanted to comment on was your station cahrt above. Very helpful - but Channel 40 is now Sony Crime, and according to my TV is going out on Channel 22 482 MHz (presumably Freeview Channel 40 was re-allocated afer yor chart was compiled).

Can anyone tell me, out of interest, does this hot weather have any effect on tv reception, terrestrial or Freeview ?

MikeP: Thank you for your recommendations, which are obviously correct, though do not take into account living in a 4 storey terraced house in a conservation area in inner London.
I before I go for Freesat I think I will try an 18 element yagi to try to up the signal enough to overcome the issue. Funnily enough 2 weeks back the Freeview engineers fitted a 28 element Log periodic which got rid of the reflections on my upstairs TV, but I completely lost reception on Channels 106-113 on the downstairs TV.
Reverting to my original 10 element yagi brought all channels back, but obviously also brought back the picture and sound glitches with the trains on the viaduct.
