The symbol shows the location of the Waltham (Leicestershire, England) transmitter which serves 770,000 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.

Thanks for your response. After some hours, I believe I have at last identified the problem.
May I first explain my aerial set up. In the past, when using analogue recorder, I wanted to be able to playback from the recorder ( located in the lounge ) to a TV in any room of the house. The aerial coax is still connected via the same system to the now digital PVR via one socket of a 2 gang plate. Loop output coax from the PVR then connects via the other socket of the 2 gang plate providing input to an amplifier in the loft. Amplifier output coaxes then connect to the TV sockets in each room ( including the lounge ).
It would appear that the aerial socket in the 2 gang plate has developed a fault. What has confused things, is that despite unplugging the cable, which inputs and loops back through the PVR, the amplifier still picks up sufficient signal to feed the room sockets, including the lounge. Hence the Samsung TV, when connected via coax, is still able to tune to channels such as 20 ( Drama ) but the PVR when coax reconnected to the aerial socket and using HDMR to the Samsung, is losing channels.
I am ordering a new 2 gang socket and trusting once this has been fitted that the problem will have been solved.
Thanks again,
Colin

Whoever set up your aerial and signal feed system made a classic mistake. The amplifier, if needed at all, should always be as close to the aerial as is possible and should always be the first active item in the system. Yours is not the first item in the system so it is amplifying not only the signals received off-air but also the signals feed out by the PVR which may include some RF feed (many are fitted with a modulator for use when there is no SCART or HDMI connection possible). So I would suggest that when you replace the dual faceplate that you investigate how to get the amplifier, if needed, into the signal feeds before both the PVR and the TV.
By checking the signal strength shown on the manual tuning page of your TV set you will then see whether the amplifier is needed at all. An ideal signal strength would be between 60% and 85%, any more would give the loss of channels experienced by some with too much signal, often shown on the TV as a message saying 'No Signal' which is misleading.

Your advice, questioning the need for an amplifier and indicating, if required, where it should be positioned in circuit, relative to the Aerial and PVR is appreciated. I will consider the possibility of amending the existing wiring set up. This was installed in the days of analogue signals and VHS recorder.
Whilst I accept that it may not be the correct arrangement now, I am not sure, given the requirements at the time, which were to split the analogue signal to TV sockets in 6 locations throughout the house and to provide video playback at all of these, from a single recorder, that this could have been achieved in a different manner.

Yes it could have been. The aerial would have fed the VHS recorder directly and the output of that fed to a distribution splitter, which may have provided some amplification to bring all the signals to the same level, and thence to each of the sockets. Note that an active splitter is not the same as a signal amplifier. in splitting the signal feeds there is always some loss involved and an active splitter provides enough amoplification to recover the signal levels at each output to roughtly the same as it would have been without the signals being split. On the other hand, an aerial amplifier is mounted as close to the aerial as possible and amplifies an already weak signal. If the signal is not weak, then no amplifier is needed. In your case it seems that you need an active splitter and not an amoplifier. Please check whether the device you are calling an 'amoplifier' is either an amplifier or an active splitter - looking up the product name/part number will help.
It would help if you provided a full post code so that we contributors can look at the predicted reception conditions at your location and hence determine whether you need any amplifier at all.

Michael: Dear Sir We are having major problems with 4G interference on most channels I have fitted the filters al800 provided waste of time, it even totally removed Sky News. I suspect that 4g are slowly increasing their ERP month by month. I have 2 quality outdoor aerials on my mast I note that the top aerial gives less 4g problems. I have spoken to al800 an utter waste of time they ARE NOT ENGINEERS just clerks and do not have a clue about the problems just post out (eventually) filters. I now intend to demand that they send a senior to carry out any work required at now charge.
Again many Thanks Mr P. Watmough 20 Church Lane Redmile Notts NG13 0GE phone 01949842687

At Redmile you are just 12km from the Waltham transmitter and should be getting a very strong signal - and that could well be the cause of your problems and why the 4G filters had no effect.
May I suggest that you check the signal strength using the facility on your TV set, usually found in the Manual Tuning option but DO NOT RETUNE. Make a note of the strengths for each multiplex. The ideal levels are between 60% and 85% - any less or more will cause the type of problems you report. If they are above 85% then you need to reduce those levels by fitting an attenuator into the aerial feed, use an additional flylead so that the weight of any attenuator does not 'hang' on the aerial input socket bon the back of the TV. Attenuators are availble in differing strengths or as a variable type that you can adjust. Shops such as Amazon, amongst others, sell them.
BTW, never give your full address on a public website such as this, that almost invites potential problems. All this site needed was a full post code and not a full address.
(As an aside, I used to live in Cropwell Bishop so I know how beautiful the area is.)

After years of normal service from my set up I now have a problem.
My aerial is set to Waltham even though Sutton Coldfield is nearer, because I'm in the East mids and not the West.
All Muxes have been fine, not as strong as from Sutton Coldfield but all over 75% quality. Over the past few months I have noticed that mux 29 has reduced to poor quality but is still stable but mux 56 has completely disappeared, no signal strength or quality, 57 is perfect. Not a real problem as due to the position of the aerial I can get the missing mux from Sutton Coldfield on the side of the aerial. Its the same on all equipment. Just wondering why its only the one mux that has gone??? Cant pinpoint when this actually happened because freeview is only used as a back up and in 2 rooms, normally use satellite.

It is likely that the current weather patterns with high pressure areas affecting TV transmissions is the cause of your problems if you have checked through your aerial system and its connections. Several areas have been so affected over recent weeks. There is nothing you, nor anyone else, can do as it is a perfectly natural phenomenon that has affected our usage of UHF signals since the start of BBC2 in the sixties when it was first noticed.
