The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 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 Oxford (Oxfordshire, England) mast?

Have allocated the frequencies yet for the post 700 clearance?
If so can you update the Oxford details please?

Hi All .

I am getting my from the through a Humax box and a plugged to the . When i check the strength for HD it says 47% - 50% but with the booster unplugged its around 26% - 29%. The signal always says 100%. Do I need a bigger to get my signal strength above the 50% mark or is this the norm. Can anyone advise on this predicament please. My post code is SN3 2PZ ( Swindon,Wilts ).
Cheers guys.

Ade Langford.

Ade Langford: Do you actually have a problem with breaking up? Which HD are you referring to, as different channels are broadcast at different power levels?

break up is intermittent and across
all HD and some SD. I have also had a 4g filter
fitted which works to a degree. I just wanted to
know if I could increase the strength to
over 50%.

Ade Langford:

Yes you could try to amplify the signals, but be care not to overdo it. Where you live is not far from where I used to live off Coleview Road and from should be reasonable. You could try a log36 log-periodic , such as this Online FM DAB TV Aerial sales (other suppliers and types are available).

If you have an already you may not need it with this aerial, but if your strengths are not over 60% then you might need it in the cables *after* your 4G filter (so that it does not amplify the 4G signals as well).

Ideally you should aim to have between 60% and 85% on all multiplexes, including the HD ones if at all possible but without overloading the SD signals from the more powerful multiplexes.

I recently started getting on BBC SD from the on my venerable (12 years old) Panasonic TH-37PE30B plasma. It was shallow diagonal repeating coloured patterns, lasted a few seconds, then it sorted itself out. I re-tuned, the same. I thought it couldn't be the , as BBC was fine on the and box from the same feed. I was convinced it was a tuner fault, and have ordered a used board for 15. Sod's Law, in the last couple of days, it's fine again! Anyone know of any transmitter work recently that could have caused it? I checked here at the time, and no reported problems. The signal strength was a good 9/10, though the TV is at the end of the aerial line. I haven't changed anything in the setup that could have caused it. I guess it could still be the tuner failing, so will probably hang on to the new board when it arrives. Interestingly, someone else on the AV Forums just had the same problem on the 42" version, which uses the same tuner I believe.

For the second day we cannot watch RT because of the very poor of the sound and image, retuning TV did not. Is somebody blocking this ?
