The symbol shows the location of the Sudbury (Suffolk, England) transmitter which serves 440,000 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 Sudbury (Suffolk, England) mast?

Carol .You live in a fairly weak signal area . You really need a good outdoor aerial.

I own an up to date smart TV set connected to a terrestrial aerial.
I live in the CO13 postal district. Very often the TV signal breaks down citing a weak or no signal..
Why does this happen ?
If its a transmitter problem , when will this be rectified?

A partial post code does not help. The Digital UK Coverage Checker, which is often our first point of reference, does not accept partial codes.

Thanks for getting the polar diagram for Sudbury, shows the big drop in signal for CH37 and CH31 in my direction (CM96HG),
Ties up with the spectrum analyser readings
Pretty hopeless much of the time on those two MUX into the evenings, again matching coverage checker.
Any ideas on why this has happened, and for whose benefit ? It all used to work fine before the 800 and 700 clearances

Put your postcode into Digital UK - Coverage checker you will see that it's the SDN and ArqA multiplexes (on UHF 29 & 31) that are predicted to have some variable reception at your location either now or in 2020. You ought not to be getting issues with ArqB on UHF37.
My inclination would be to check your aerial installation and coax connections & do you have the correct group or high enough gain aerial? Also check you don't have any boxes (VCRs etc) with RF outputs down near those channels.

Yes it is the correct aerial, have tried a couple I can get to both a K (in use now) and a W (replaced an E at the 800 switchover in 2018).
I can also see the power drop from previous spectrum analyser plots of the W that saved off when I aligned using the SA after switching from the E.
C29 is indeed flaky at times too, as the predictor expects.
I am not aware of any C37 blockers, but will check again as that is of course the old RF VCR frequency.
My question was more why has a special radiation pattern been put in now, and how did a change that makes reception worse get permission ?
A coverage map by MUX would be interesting to see.

I'm not sure that the radiation pattern has been changed recently. In any event that will be taken into account by the coverage checker. Because of the 700Mhz clearance see Digital UK | 700MHz clearance and the number of transmitters using a smaller number of UHF channels, then this will affect reception of some channels from some transmitters in some locations but again this will be taken into account by the coverage checker, maybe you need to enter your house number to get a more accurate prediction.
It's also possible you might have some very local issues affecting reception - a tall building, trees, nearby water tanks or solar panels, other nearby metal objects etc can all affect reception of signals.
Although it could depend on which Wideband aerial you've got, generally the Group K will have better gain at the low end of the UHF channels.
If you enable Pro Mode by the coverage map at the top of the page, you should be able to look at the pattern for each multiplex (click in the list), but again, as already mentioned this should be taken into account by the coverage checker.
If you have any devices with RF outputs, I would set them above UHF56.
