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 you

we are experiencing a sudden loss of channels in the Mevagissey area and wonder if our transmissions are coming from another transmitter, can you suggest why this is happening please?

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.

simon: 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?

Callum Precious:

Well, I'm afraid without a full postcode, the approximate direction (compass bearing) that your aerial is pointing and whether its rods are vertical or horizontal, also some details of a selection of channels that are affected and what the problems are, no-one will be able to help.
