The symbol shows the location of the Guildford (Surrey, England) transmitter which serves 48,000 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 Guildford (Surrey, England) mast?

I have Freeview from Guildford (in Chilworth). Although reception is good on our main set, on a second set my wife sometimes used in another part of the house (at the end of quite a long extension cable through the loft), it's patchy, with a lot of breakup. Is this likely to improve after DSO?, and our aerial being quite old I have been considering replacing it. If I do, what challel group should I get?

Sorry for two questions.

Mike

Mike O'Sullivan: After DSO all muxes will be transmitted at 2kW, so yes you should notice a considerable improvement in signal strength. It is possible that the problems with reception on the second TV are caused by interference picked up by the coax if the screening is not very good. If this is the case, replacing the extension with satellite grade double screened cable would show an improvement. If you do replace the aerial, all frequencies will be within group "B" after 18th April 2012.

Many thanks for the info. I have used "satellite grade" co-ax cable, unbroken length properly terminated with 'F' Connectors, but the length is a factor I'm sure.

Mike O'Sullivan: Just to add to that already said by KMJ, although its not worth altering anything at this late stage the problem you are experiencing is nearly always found in cases where the aerial has been split without using a two (or more) way powered splitter, as this is the only way of ensuring that the signal received by each device is at roughly at the same level.

This said of course assuming (maybe incorrectly!) that a powered splitter isnt used.

However as KMJ has suggested, come switchover to high powered operation your problems will most likely vanish.
