Bruce: You are indicated as having a clear line-of-sight to the Hannington transmitter (@ 11 miles) and with no obstructions whatsoever being seen as far as the ground is concerned, trees or any man made objects excluded! and so in theory you should be receiving a strong signal.
This being the case I am inclined to agree with MikeB's line of thought insomuch that the engineering work recently carried out at the station "might" have resulted in a very slight increase in the erp level being radiated from the mast, and although this would be neither here nor there and indeed not even noticed on most installations, however it "would" be on any installation that was already running with a very high signal level bordering on the excessive, as the slight increase in level could trigger problems in the tuner by overloading its RF input / mixer stage, the symptoms of being exactly as you have described.
That said, the misleading aspect of an erratic signal problem is that the symptoms of a slightly "over the top" signal level are almost identical to that of the reverse situation where a signal is hovering around the lower cut off threshold, this being where anyone not equipped with proper signal level meter is at a positive disadvantage as the indications given on a TV or boxes signal check screen can be totally inaccurate due to elements of instability affecting the measuring circuitry and with the said errors always resulting in much lower levels being seen over what in reality they actually are, this being due to the measuring circuitry only decoding the uncorrupted parts of the data and ignoring the remainder and why the signal quality (bit error rate) appears to vaulting up and down.
By the way, its not possible to electronically bypass a mast head amplifier, and so if the device is not easily accessible then the only thing that can be done is to fit a cheap variable attenuator (under £5.00 from e-bay outlets) in line with the aerial socket on the TV or box and adjusting accordingly, but though I would not advise doing anything until you can verify as to where or not the problem is possibly widespread in your area or is only confined to your own installation, this obviously achieved by checking with others nearby.

MikeB and JB38 - thanks v. much for your comments. I know I am only 11 miles from the transmitter, and usually I get a good reception including HD - thats my point. Suddenly I am not. Actually my house (in Newnham) has always been in a marginal reception area - I am almost due East of Hannington (100 deg actually) and maybe the mast output is directed more SW/W to avoid clash with Crystal Palace or Guildford. This is not the first time this has happened either but never lasted this long. I checked with a neighbour - same problem, he couldnt get any picture (but uses freesat by preference and only uses Fview when sat signal bad so hadnt noticed. I am highly sceptical but I will bypass the amp. and try connecting 'direct' in case its amplifying cross-channel interference from other masts causing the probs. Will post back here when done. I do accept that I have always assumed weak signal to be the issue not the opposite (stems from before the switchover!) but my neighbour also uses a Masthead amp so I accept that with this in common I have to "eliminate it from my enquiries".

jb38 mikeb - large amounts of humble pie being eaten here! I took my masthead amp off the aerial this morning. All channels receiving at full strength or thereabouts, but no errors or pixellation and HD channels back also at full strength and crystal clear. So my scepticism completely unfounded and problems def. had been caused by an already-strong signal being amplified unneccesarily. I think what threw me was that the Masthead amp was a variable gain one, but even when turned right down the problems remained. Will inform my neighbour with same problem of the fix. Thanks to you guys for your good advice though and the courteous dispensing of it! Happy customer....

Bruce: Many thanks for your update on the situation and pleased to hear that you have now returned to being fully operational, however, and without wishing to appear as the classic doubting Thomas, but there is another angle to your reception having returned that is based on the fact of you having said that turning the gain of the amplifier down had no effect on the signal, and being that its possible that the reason for this is because that the amplifier had failed, hence the control not having any effect on the signal.
My only reason for saying this is that aerial amplifiers can and do fail, especially types that are mounted in the loft (should this apply in your situation) as long periods of prolonged heat can cause the transformer in the power supply to fail, therefore it might be worth testing the amp out prior to informing your neighbours just in case the unit is defective.
Of course if your reception is OK without it then obviously it is not required anyway, but purely for verification purposes it would be worthwhile testing it out by placing in line with your TV's aerial input socket and "with its gain control fully advanced" witnessing if any changes are noticed in reception when its powered up or vice versa, because a faulty device will not show any changes.
The point to note being that a defective amplifier in line with an aerial circuit will act like an attenuator.

Bruce: Glad we could help, and JB38 has pointed up the possibility (which hadn't occured to me)that the amp wasn't working properly in the first place!
Hopefully you neighbour will get sorted out as well. I must admit to finding it a little strange as to why anyone thought you needed an amp in the first place, but at least you sorted it out easily.

Bruce: Just as a follow up to that said in my reply, should you decide to test the amplifier out the using the method suggested then carry out the powered / unpowered check whilst your TV is sitting on its signal check screen on the channel chosen for the test otherwise if any differences are evident they might not be noticed.

Hi, I am in Liphook (GU30).. Tonight we have no signal at all, other than 'blips' occasionally. Having checked my installation throughout, it only occurred to me to ask my neighbours about their reception while I was in the loft! Our Hannington-pointing neighbours are reporting the same. Online showing no reported problems at this transmitter - is anyone else having problems? Surely not 4G at this site?

John: Hythe SO45 we use Hannington, also intermittent problems, no BBC chs, channel 4 and 5 also playing up
