Is the transmitter output the same in all directions?Radiation patterns withheld
I live in EX108PA using the Beacon Hill transmitter (Sidmouth). My BBCa signal is transient /very poor /non existent , others are fine.. My aerial was installed some 10 years ago and has a mast amplifier and in house amplifier / distribution.
Any ideas on how to solve this

Tom Thornhill :
You are right on a fringe for any reception from Beacon Hill, I need to look at this in more detail.
When did this problem start? Is it intermittent or continuous?
Are your signals normal in the daytime?

Tom Thornhill :
This is a tricky one. Nether the BBC nor Freeview predict any useful reception from Beacon Hill, whereas they do from Stockland Hill (roughly to the NE, compass bearing 35 degrees) which is closer (17km) and has a higher power, however there are major very high ground obstructions on that line of sight and the BBCA predicted reception is (very) poor, I'm not even going to go there with assessments.
If you are far enough south in your postcode with a good aerial height, then although Beacon Hill is 37km away, you will have line-of-sight. With unfavourable aerial sighting the likely local obstructions will come from Peak Hill, I think it's called, then further afield - high ground between Ladram Bay and Budleigh Salterton.
I assume we can confirm your aerial points at compass bearing 226 degrees, that's ~SW with its rods (or squashed Xs) horizontal. Check that it's still pointing correctly and that the coax downlead isn't degraded (sheath brittle and damaged) and it's not flapping about in the wind. Check all your coax plugs are correctly plugged in and corrosion free.
An issue you may have as you have a masthead amp and amp/splitter is reception from the Sidmouth relay 1km away but it is only 12W (very very low power) to the back of your aerial - compass bearing 72 degrees. Although it's vertically polarised you could still probably pick it up on your aerial with a poor signal.
Beacon Hill transmitter was listed for Planned Engineering last week (but isn't this week) and if you retuned at any time during that if you had no signal or badly pixellated pictures (never recommended) you may have become incorrectly tuned perhaps picking up Sidmouth.
So check in your TV Tuning Section that you are correctly tuned to Beacon Hill's UHF channels.
These are C44, C41, C47, C42, C45, C40 that's in multiplex order -
BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6
As your aerial is 10 years old, there's a chance it will be a Group T/Wideband whereas ideally it ought to be a Group K (rather than a Group B) although they'll all work, you ideally don't want to be receiving any signals above C48 since the 700MHz Clearance as this is where new/updated mobile signals may appear and could give interference. If that happens you can get free filters from https://restoretv.uk (put your postcode into their checker if this problem arises).
I can't find any current faults listed for the Beacon Hill transmitter, but there is some weather related Tropospheric Ducting about, which might cause occasion temporary interference from distant transmitters (do Not retune).
