I should add my post code is IP1 4HL and, all aerial connections checked, if I reset my freeview channels early in the evening I only get around 22 tv channels - the only watchable are the BBC's at that time. If I reset late at night around 1a.m I get well over a hundred when all the missing ITV, Channel 4 / 5 and other freeview miraculously work. There was no problem last year up until around this new year, even though I have had a loft aerial set up with amplifier for many years.

Hi there. Yes large buildings in the line of sight aren't helpful! However, let's hope the main issue is only the Planned Engineering work at Sudbury with "Possible weak signal" which is still continuing this week.
Amazingly even the Freeview checker is mentioning it if your put your postcode into the box on Freeview | All your favourite TV shows, all in one place and all for free and you can also go to the Planned Engineering works page.
It is unusual for work to carry on through an evening, but surprisingly that you've got a sufficiently weak signal as you are normally predicted to get excellent coverage from Sudbury.
The issues over New year were due to an unusually strong bout of Tropospheric Ducting (see Effect of tropospheric ducting on Freeview | Help receiving TV and radio ) which sometimes comes with high pressure. It isn't normally as strong even in summer!

Many thanks for your reply. I have looked up the links which will prove useful in the future.
I think my problems may be connected to work on the transmitter as well as the new Sproughton road warehouse which is far wider in profile than the old silos to my location. Yesterday non-BBC channels were slightly improved much earlier in the evening - well before the approx 10.15p.m change of previous evenings which seemed to be like someone switching on a booster somewhere!
Anyway - thanks!

Are you still having to point your loft aerial through a party wall? Is there no position you can put it in that would eliminate that or go over the edge of it?

Long term if we have major problems I may have to have an aerial mounted outside, probably on the chimney stack. I currently also have a 360 degree radio aerial connected to the one down line which has meant certain tv channels are now weak or non existent. Fortunately I'm not over enamoured with freeview tv and its endless repeats coupled with ads for nothing I'm interested in, so I get by!!

I hope you've got the FM aerial connected through a VHF/UHF diplexer. It will have some insertion loss of course. Have you checked all the connections recently, make sure they are clean and free of corrosion?

All connections are fine. I have an amplifier at the room end with separate outputs for tv and radio. In the loft the radio aerial cable is connected to the terminals of the tv aerial.

You cannot connect two different aerials together that way and that will be one cause of your problems. You must use a proper coaxial diplexer.

What you need is something like this eBay item 264646940009 but can I find a new one or similar by a different manufacturer at a "sensible" price!! These things used to be widely available, two a penny!
In that example you can remove the existing "leads" and connect your aerial and downlead coaxes directly to it.

OK, found this https://staks.org.uk/prod…uhf/ nice low insertion loss.
Don't know if they'll supply retail, give them a ring (0)28 9146 9136
With a bit of luck they'll send it Royal Mail 2nd class, total inc postage may be under 10.
