The symbol shows the location of the Tacolneston (Norfolk, England) transmitter which serves 330,000 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 Tacolneston (Norfolk, England) mast?

TinaE: The question is simply one of is it the aerial system (up to the wall socket) that is at fault, or is it beyond there (i.e. your own part of the installation)?
If it's the former then it's the responsibility of the party which looks maintains the aerial system to rectify it and it's therefore outside your direct control. If the signal level is too high then that's an issue with the aerial system and can therefore only be addressed by adjusting the system.
The fact that a neighbour uses the system without issue to the picture and sound doesn't necessarily mean that it isn't at fault. With digital reception it either works or it doesn't, with very little in between. Differences in models and different lengths of cable could possibly make the difference between "only just" working and "only just" not working.
If there is a 4G base station operating in the 800MHz band (just above what's used for TV) and it coincides with the start of the problem then this can't be ruled out. However, what a base station means is that there are mobile devices in the area which are transmitting. I wonder, could your neighbour be using such a device at those times? Perhaps the signal is so strong where your wiring is that it's being picked up in your wiring -- just a thought.

Thanks guys for your input. Hmmmm. Well I've ordered a cheap attenuator to give that a go but not hopeful. If the signal is too high then surely I would have experienced problems from day one when I moved in? That's not been the case, it's only been in the last month so there is a factor that has changed in that time but how to work that out factor has changed? Today has been a really windy day in Norwich and this evening everything is pretty much gone with my signal. Does that tell me something? Sometimes if I stand and move around the digibox and the tv in different places, when experiencing signal problems, that can make it worse. Does that tell me something? And how to diagnose if the problem is up to my aerial point or beyond I'm still none the wiser. I don't own a smartphone and neither does my neighbour so neither of us are causing 4G interference. God I miss old school analogue TV! Digital being better is such a con!

TinaE: Ok - you've suggested that if you move the various parts of your system around, you get worse reception, and the wind might be a factor. If the wind was causing problems, then you'd expect other people in your block to have similar problems, although, as David points out, different TV's have different tuners, etc, so its not impossible they are just about Ok, whereas your not.
However, David also pointed out that the problem could well be within your flat - a dodgy aerial lead or socket (which might explain the problem when you move the digibox around).
First thing - check your signal strength and which transmitter your tuned into. If its getting towards 100%, and keeps going towards very low and then very high, then its likely to be too strong.Remember that a transmitter might have been steadily getting more powerful, until it reaches a point that is just too much for your TV's tuner.
If its continually very low, than there is a problem with your system. All you can do is check each part of it, until it becomes apparent what it is. Start with the aerial lead (new ones are really cheap), and just make sure that nothing is loose.
Actually pretty much the same thing might have happened with analogue TV as well. A dodgy socket or cable would have been much the same problem if there was just analogue, the picture would have been snowy rather than blocky.

TinaE : Although MikeB has covered various possibilities, but variations in reception when moving about a room is something only really experienced when using an indoor aerial, if though an aerial of this type is not being used, then its usually an indication that the continuity of the braiding around the coax is broken at some point, because as soon as this happens the coax becomes part of the aerial system rather than just carrying the signal from the aerial.
Loose fitting coax connector plugs when plugged in, can also cause this type of problem, likewise if the braiding earthing screw on the "rear" of the wall plate outlet socket has not been fully tightened. Another possibility being if a "F" screw type connector has been removed and refitted without the outer having been screwed back in again, this if responsible, more likely to have happened at the distribution amplifiers side of the equation.

TinaE: JB38's advice is excellent, and makes an important point - it sounds like you have a portable aerial.
Since we have no idea of your system, etc other than the information you supply, which makes any diagnosis difficult. could you supply the following:
You say you live in a block with a communial aerial. Is this a freeview aerial system, does it have a booster, does anyone else have a problem, and do you actually use it?
If you have another aerial, such as a indoor aerial, do you use that instead? And if you do, how is it connected - via a digibox, etc?
And what is the signal strength/transmitter the TV/digibox is tuned to?
If we know these facts, we can help get to the root of the problem, or at least narrow it down.

My Freeview now has a mind of its own. Sometimes it removes BBC channels and other times ITV. No matter how many times I follow the Freeview rest procedure it will only load the channels it wants to. I have called out the local aerial installers they say there is nothing wrong with the equipment . This has only been happening for the last six weeks or so prior to that all was well.
My Postcode id NR14 7BU has something changed in this area ?
Any suggestions ?

Alan: As Einstein said, insanity is doing the same thing and expecting different results.
The local Norwich TV channel Mustard launched on 24 March, according to a BBC News report. The signal, which broadcasts from Tacolneston and in the direction of Norwich, probably came on air a few weeks before the station did. Maybe this is the factor which is causing your issue.
We get reports of receivers which forget some of their channels when powered down, and this is often due to the device running out of memory. It happens where the desired UHF channels (frequencies) are high in the band and unwanted ones are lower down, the latters effectively taking the memory that the formers need. The answer, therefore, is to prevent it from storing the unwanted channels.
Try having the aerial out for the first 30% of the scan or up until it gets to UHF channel 30. If this doesn't work or there is another issue then post back and I will make further suggestion.
The other option is to wiped what's stored by running the scan through with the aerial out and then manually tune.
For Tacolneston:
PSB1 - BBC One - C55
PSB2 - ITV - C59
PSB3 - BBC One HD - C50
COM4 - ITV3 - C42
COM5 - Pick - C45
COM6 - 4Music - C39
COM7 - BBC Four HD - C31
COM8 - C37
L-NOR - Mustard - C57
Note:
- "C" numbers are UHF channels.
- PSB3, COM7 and COM8 are applicable only for HD receivers. With manual tuning if there is an option for DVB-T or DVB-T2, for these it needs to be set to the latter.
- COM8 is probably not on air yet.
- As L-NOR is directional you may find reception either non-existent or intermittent, this being suggested might be so by the Digital UK Coverage Checker.

I live in old Costessey, Norwich and I have no freeview channels for TV and other channels. What is happening in the area or is it my airier. I retuned my TV and lost a large number of channels including ITV and Channel four. Can anyone offer an explanation .

Mark Chadwick : Your just 16km from Talcneston, and DigitalUK reckons you should have a great reception. Logically, the first thing to check is your aerial - if there is a broekn cable, etc, then that will obviously mean a total loss of signal. Try just replacing the old aerial lead from the TV to the wall - cheap and easy to do, and that might be the problem.
Unfortunately you retuned the TV. assuming it was on the correct transmitter, you've possibly retuned it to an incorrect one, much further away, and only just enough to lock on, but not enough to actually get you a working signal. Since Talcneston is a much higher frequency number than the rest of the possible transmitters, thats possible. Try manually tuning the TV in and see. If it works, great, but its highly likely that your aerial system isn't working perfectly.
