Thanks. I've just realised I got this wrong: I bought a 52 element aerial and found it far too big for the loft space; returned it and bought a "30 element high gain wide band digital aerial" which - until very recently - worked very well. I can't help thinking that something has changed, or that some component isn't working.
Have you any ideas?
Thanks for your thoughts so far.

Hello. I live in OX2 6RB. I get good reception on BBC A and D3+4, with unpredictable reception on SDN - today it is just about OK, with slight, occasional picture break-up. BBC B, ARQA and ARQB have disappeared completely in the last three weeks or so.
The missing programmes used to be fine, with good coverage on all for the three TVs in the house. I have been re-tuning from time to time. Two of the three TVs are digital e.g. Panasonic TX L24E3B; the other has a digibox/ recorder.
What can have changed?
The signal from a "30 element high gain wide band digital aerial" installed in July 2009 (firmly anchored inside the roof space and aimed at the Oxford transmitter) is split into 3 separate cables - one for each TV - with a Labgear UH141 UHF antenna distribution amplifier. I have a separate 12V DC masthead power supply near the aerial, powered by a nearby mains socket. This appears to be working.
ITV4 and History Channel have just reappeared, with frequent picture break-up. The Panasonic TV is telling me that the signal strength is strong but the quality is very low.
Either something has changed, or some component isn't working.
Have you any ideas please?

This is for Dave.
On June 1 you wrote:
'By using a high-gain aerial you have reduced your acceptance angle. So if the (average) quality over the angle which your aerial works is lower than had you used one with a wider acceptance angle then you will have a lower quality signal. It is a possibility that some object(s) have changed, such as vegetation in the signal path growing.
I think that you should try feeding the output of the aerial directly to one of the TV feeds (sockets), bypassing the amplifier and see if it improves.'
After yet more deterioration/ frustration I finally got up into the loft yesterday and tweaked the aerial back to horizontal (it had sagged a little) (1) and bypassed the amplifier (2). First made no apparent difference. Second - BINGO! Suddenly I have 94 stations and home life is peaceful.
Thanks!

Hello
I am about to move to a two-storey terraced house in OX6 2EW, and am wondering if once again I can get an aerial mounted inside the roof space to get good freeview reception. The roof space - which is far more spacious than the last -- is at around 74m above sea level, and the row of terraced houses which includes mine runs approximately E-N-E.
If this is feasible, what kind of aerial and related hardware would you suggest?
Many thanks
