I just installed a loft aerial in GU27 pointing at the Guildford transmitter, connected it to a new Technika TV and did an auto-tune. I am getting a good signal (89%) from all MUXes except from COM5 ArqA which is pretty much 0%. I'm a bit confused why this one MUX would be so weak when the others are so strong.

Any ideas?

quitequick: Could it be the co-channel signal from Heathfield? If so, could you re-site the aerial where it picks up the interfering signal less?

Last May I fitted a 12dB High Gain Aerial on
my roof, it seemed ok but just lately the
reception is bad, sometimes no signal at all.
Do I need a 48 element aerial?

I have changed my digi box as my digital
recorder could not cope with the interference.

Roger Huxtable: Your location is indicated as being able (in theory) to receive about the same level of signal from either the Guildford transmitter (@ 6 miles / 316 degrees) with aerial mounted vertically or Midhurst (@ 13 miles / 218 degrees) with the aerial being mounted horizontally? would you know which of the two applies?

The way to check being to carry out a signal test on BBC1 and note the mux channel number shown along with the strength / quality indication, Guildford being Ch43 whereas Midhurst is Ch55.

However irrespective of which of the two you are receiving from its noticed that the signal path from both sources is being obstructed by reasonably dense trees, these not just being in the immediate vicinity but at various points along the way and which could well be responsible for your problems by intermittently blocking the signal, should this be the case then a so called higher gain aerial is very likely to make the situation worse by the fact that high gain aerials are only that because they effectively focus on the signal, but if this is being obstructed / scattered by being reflected from the trees then a wider pick up aerial such as a Log type used in conjunction with a high gain variable booster is more likely to improve the situation, albeit that it will never be perfect.

Further advice dependant on reply.
