Below are all of Nick's postings, with the most recent are at the bottom of the page.Many thanks again JB. Log periodic are not for fringe areas though, so I think I might be better off with a large yagi, even if it is designed for group B. Aldeburgh is not technically within Sudbury's area.
I suppose I could have two aerials to cover both groups, but would probably lose out connecting them together. What a lot of problems are caused by a weak regulator who does not force high power relays to take all channels, and similarly allows freesat, set up to cater for those in poor areas to do the same.

JB, do you know about DAB radio? We have a similar problem at Aldeburgh, a transmitter that carries only the BBC channels. I was thinking of trying to get the other channels from Mendlesham, but it seems even the transmitters that do provide all channels transmit the commercial ones on lower power. Do you know why?

Thank you gentlemen. The issue of aerials is quite confusing. If you go to ATV aerials site, they say the opposite, that a low gain aerial with wide acceptance angle plus booster is a poor substitute for a high gain aerial. But they do like log periodic, in areas of good signal strength. It also seems to be that boosters can do more harm than good on digital.

Thank you Dave for your trouble in giving such a full answer.
Now let me throw another thing into the pot. I have recently been posting questions on the Tac site as I believe the mast height has been increased and coverage extended since going digital. I was advised that Sud is still my better option as at 10m it is technically line of site. So in theory the answer would be to get a good set of binoculars and see if it is!

Please could someone let me know if this transmitter will carry commercial stations and if not, which transmitter is most likely to be receivable which does?

Dave and JB, you are being very helpful, thanks.
Another one. A booster is less use the further from the aerial it is placed as it amplifies a lesser signal the further along the coax it is until putting it behind the set appears to do nothing.
Why then do they put them half way or more down the pole, rather than, for instance, behind the reflector?

So arq b is on ch63, not 50+ currently? And the power greater than in the main table? And then will move to 56, so a particularly wideband aerial will not be needed?
Thanks Dave and JB.
