The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Oxford (Oxfordshire, England) mast?

Have been looking more closely at my location in relation to Oxford transmitter and mobile phone masts. Apparently 2 EE phone masts within 1.5km of my address and seem to be broadly right behind my aerials line of sight to transmitter. Notes indicate ArqA in higher risk range for 4G interference. Could this be cause of my problem?

MH: The easiest way to find out if it is 4G, is to call at800 and ask if 4G is operational in your area, which it most probably isn't, and to check with neighbours as Paul mentioned, as they will also be suffering problems.

No indication on at800 that 4G operational in my area at present and immediate neighbours confirmed no Freeview issues with ArqA C59 programmes all OK, including Sky News - they have aerial in loft, mine is higher up on chimney breast.
Seems to be single multiplex problem that suddenly developed on Wednesday.
Lagbear distribution box in loft seems to be functioning ok and the RF Out on my Sky box is set to 40, which should not cause any conflict.Have also done freeview reset.
Signal Strength/Quality as indicated by my Toshiba TV for each multiplex are:
C50 Midway between Weak & Average/Poor
C53 Average/Average
C55 Midway between Weak & Average/Poor
C59 No signal
C60 Strong/Good
A very mixed bag og strengths/quality.
Looks like I will need to get someone in to sort things out.

Well, the weather has deteriorated; black skies, pouring rain, howling wind and, with it, comes a degraded television service. Film 4 is beyond unwatchable. A quick flick through the TV channels shows a similar story elsewhere. What was the line about digital TV providing a superior service? OX28 5JJ.

If the wind and rain make your TV reception worse, are there trees between the transmitter and your aerial? Wet moving leaves can cause problems.
I don't know: what was the line about digital TV providing a superior service [to analogue]? Digital has more channels than analogue and no ghosting, but digital TV's behaviour with a weak signal is more annoying that analogue TV's behaviour.

Brennig/Paul: The most common explanation for rain causing degradation to Freeview viewing is that rainwater is getting into the cables.
This can happen if the aerial has been moving around and opened up part of the construction, or - as is more common - the cable has deteriorated.
It's often best to use satellite-grade cable from the aerial to the receiver as this higher quality cable keeps out water much better.

@Paul, @Briantist
Thanks for getting back to me on my gripe.
My aerial is in the loft. There is no external installation.
There are no trees or other objects obstructing line of sight (outside the house).
This is a new (5 year old) house. When I had the aerial checked because of pixelation on the switchover to digital, the installer said I had a strong signal, and he removed the booster. Pixelation stopped, at that stage.
When the picture/sound deteriorated the other day, I had a quick (far from exhaustive) flick around the channels and deterioration was obvious on:

Brennig: The terrain plot suggests that objects on the ground at High Cogges could be an issue:

Also, what about the industrial estate near to you. Has a building recently gone up, or been modified in some way?

We have loss of whole groups of channels when
certain weather conditions occur.
Is it called "inversion"?
Caused by low power on the commercial channels
from Oxford and unless they increase the power it will never get better I am told!

Algy: There is, since switchover, a two-tier terrestrial television transmitter network.
The coverage of the Public Service (PSB) channels (in theory) mirrors that of the former four-channel analogue network.
The Commercial (COM) channels fit in where possible and where the licensees wish to pay for transmitters. The channels/frequencies given to them are re-used in closer proximity than the PSB channels are re-used. Consequently, they are more likely to be limited in their coverage by interference. This is where the signal is present, but that there is another transmitter that is co-channel and so degrading (interfering with) the wanted signal. This is why the transmission power of the COMs is lower than the PSBs.
The Andoversford relay transmitter is co-channel with Oxford's COMs, albeit vertically polarised. Perhaps its signals are carrying further, at times, and this is what's causing your difficulty, although they are on very low power. It might be worth seeing if neighbours have the same issue.
You are, as you say, high up and appear to have quite a clear path to Oxford so the lower power COM channels may be otherwise perfectly adeqate to reach you.
The high ground at Blackheath Clump, north of Burford, is in your first Freznel zone (look it up), as the terrain plot shows:
