Nick: What was said is of course referring to reception from Sudbury, as yes! as far as aerials are concerned there is similarities when comparing the two mentioned, but in your type of area its more a case of careful positioning of the aerial, and with that not necessarily meaning at a great height but to the left and right of say gutter mounted positions if an up and downstairs height is being referred to. ((i.e; about 16 feet or so)

Nick: At the top of the page, under the heading "After switchover frequency notes" there are references to "mid-2012". These dates have now been finalised and the events are due to take place on 27th June.

I assume that at the time the text was placed on this page, the sources did not have a specific date.

However, if you refer to Digital UK Tradeview predictor, you will see that it is now 27th June that the changes will take effect.

Also refer to Ofcom's licences document, V7 27th January 2012 which gives the date that Sudbury's COMs are due to increase in power:

Briantist: Can you update?

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.

Nick: Just a small correction to what I mentioned, ArqA is at 3kw and not 2.2kw, although in real terms as far as reception is concerned its a bit academic except in situations where the signal is just making it above the receivers reception threshold and no more.

ArqB has been on Ch63 since the latter end of 2011, and as far as your aerial is concerned, as Sudbury's channels span from 41 - 60 (pres 63) after June 27th then if you want to be fussy a group E (brown tip) aerial is the exact grouping, but a log 40 or similar would suffice, all logs being wideband.

Dave Lindsay/jb38: With the proposed increases in Freeview Mux's & channels is it not the case that, in the end, all aerials will need to be wideband?

Kevin Hodges: Well yes, you are basically quite correct on this point as far as main station transmitters are concerned, and so a wideband aerial could be said to cater for all eventualities, and with the only stations that can be excluded from this being the PSB only Freeview "light" relays, as they are likely to remain that way for the foreseeable future.

OK, since Q3 last year in CM2 I lost ITV 4, Film 4 etc and I know it's not coming back til June 2012 but.. I noticed Sky News breaking up recently, re-scans fail to find the channel so it's gone now, nothing has changed on my end all the equipment is post May 2011.

Has there been anther dip in power from Sudbury at all?

Brian O'Keefe: The Hertford relay, as part of the Crystal Palace group, completed switchover last Wednesday when it began to use C54 for digital. It had previously used C54 for Channel 4 analogue.

Now that Crystal Palace has switched and is on full power, you could try manually tuning to its ArqA on C22 and ArqB on C28. You may be able to receive these off the back of your aerial until Sudbury goes to full power.

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?
