john evans: As far as your problem is concerned, maybe you could clarify on the following points.

(1) : If the reason for temporarily moving the aerial involved builders, was it them who actually moved it?

(2) : Were the coax cables disconnected from the aerials before the pole was moved?, or was the whole structure (inc aerials with cables attached) just temporarily moved out of the way?

My only reason for asking being, that my initial suspicion would be along the lines of the problem being caused by a faulty coax to aerial connection, or that the cables have been damaged, because by being located at just under 2 miles away from the high powered Divis transmitter, reception should be possible (in theory) with only a short length of wire (3-4 feet or so) connected directly into the aerial socket (circular middle) of your TV or box. (Black Mountain excluded)

Jordan woods: Hi, Jordan. I explained in a post to Margaret Jones yesterday why this is. I will re-iterate here. 'Keep It Country', channel 87, is now one of a group of channels that you can only watch if you have high definition (HD) receiving equipment. A standard (SD) television or any old tv connected to an (SD) Freeview box is unable to decipher the channel 87 signal into a watchable picture and audible sound. To get 'Keep It Country' nowadays, you need either an HD tv set or an HD-ready tv set plus a Freeview HD set top box. You can get an HD set top box online for ?43 plus delivery. I f you do, make sure your tv is HD-ready, has an HDMI connection and that the new Freeview HD box comes with an HDMI lead included. One other thing: you need to be using a transmitter that transmits the 'Keep Country' group of channels, called 'COM 7'. Not all transmitters transmit it, which is why i'm telling you. Hope this all helps, Richard, Norwich, Weds 15th. June at 8:45 a.m.
