Nick: A group B is unsuitable for digital reception before or after switchover from Sudbury, no matter what the "gain". See "Transmission frequencies" above.

Dear Brian,
Group b covers ch 35-53, ie all the analogue channels used by Sudbury. I do not understand how a wideband areial would improve things as it must surely be a compromise to try to include channels as far apart as 21 and 69. I have seen graphs of the performance of wideband aerials which show a tailing off of gain at either end. Surely that is exactly what my group b aerial does too?.
I am still playing with the digibox which I have set to install. When the wind is in the right direction, I get channels from ALL the mux shown for Sudbury, but not all the channels within every mux. This really puzzles me. Notable absentees are ITV 1, c4 and C5. Whoever decided we should have QVC and Babestation instead!

Nick: Well, apart from the rather obvious point that C54 and C68 are not covered by a group B aerial, thus the need for a wideband aerial.

Hi Brian. Just reading about aerials, and it got me wondering about mine. A few years ago I fitted an Antiference XG10EW aerial, but no indication on the box as to what group it belonged to (I know it's a Class2), only that it's for UHF channels 21-68, so I guess it's a Wideband, and should be adequate for the Sudbury switchover in July? It's worked very well so far here in CO14 8AW, where we're a bit on the edge of the best reception!

Thanks Brian,
looks like I gave you duff info, receiving nothing on ch 68, despite its higher power.
Will have to wait till upgrade to see if we get it before changing aerial. I assume that it will still be 68 for these channels after upgrade? I don't know why they had to put them out of group in the first place, esp as they are far more important than QVC etc.
Kind regards.

Nick: As above, the final channels are C41, C44, C47, C49, C56, C58, C60- which means C56, C58 and C60- are "out of group" so you must have a wideband aerial if you want all multiplexes from this transmitter after switchover.

Tim Chase: You are not really in a good reception (or "marginal") area, but if the aerial is working for you now it will continue to do so.

You might want to consider Freesat if you want reception 100% of the time - Freeview and Freesat are a good combination.

Nick: The aerial group with best performance for C68 is group E. Although C68 is not used after switchover stage2, a group E receiving aerial would be suitable for the post swichover frequencies. The Digital UK postcode checker shows your freeview reception to be variable at best (with all muxes at full power from 27th June 2012) and currently does not offer a prediction at your location.

You have both been most helpful. It looks as if after upgrade, all the 'proper' channels will be within group. Here we get A1 signal on analogue, with good aerial and booster, the only problem being various forms of interference at times, which it seems will diminish with the continentals now digital and the rest of the uk xmitters following.
I have got a lot of info from a site called atv aerials, confirming my view that wideband aerials may bring in out of group channels but that within group will be worse, making it debateable to change what I have.
I am still hazy on the subject of signal quality. If the booster makes C5 on 50kw A1, no noise, does that not mean signal quality is good? My digibox does not show sig quality, only strength.
