Is your main aerial polarised horizontally or vertically loft or externally mounted,and is it also a group A aerial (tipped red) or a group W wideband aerial (tipped black).
One possibility could be that the aerial co-ax cable needs replacing if it is rather old as HD broadcasts do give somewhat poor performance on old co-ax aerial cable.
Once again i apologise for my incorrect location as such on my above text. F

Now get blochy/bad signals, one set top box will not even try to tune in this set of channels.
I notice that the signal is very weak compared to others WHY? I understood that with all this retuning the signal strength would INCREASE, hence BETTER reception, why is this not the case?R

The mast located on Capel Brithdir which is near Rhymney. What is the average amount of homes that it cover, and with a switch over, are these masts going to be taken down, or stay as a wavelength stronger point, which in that Case, in the property where the mast is located there's several ther masts there which is smaller what is best described as aria.s, are they a Emergency service aerial which Wenvoe operates, Thank youM

m g hunter: A common reason for a relay transmitter going off the air is because of a power failure. It wouldn't be expected to be engineering work at this time.
If you receive your TV from the Mevagissey relay, then there may be clues of the power failure. Burglar alarms on properties that are also affected may be sounding. The Mevagissey site is also home to base stations for four GSM mobile phone networks and 3's 3G network, so if you have no or much lower than normal signal then they too will be likely off the air. S

Rossendalesimon: Possibly.
The Digital UK predictor suggests that you might (predictors cannot ever be absolutely accurate).
Also, have you looked to see what are neighbours doing? updates
