Nick, for what it's worth I've a wideband 'X' beam aerial in the loft (feeding the TVs via a 4 way amp) and pick up all the Sudbury mux's loud and clear here in sunny Chelmsford. I assume that with the long term proposals to increase the number of mux's all aerials will need to be wideband

Nick I've lived in the Woodbridge area for many years. TV reception has always been a problem in several areas of the town and surrounding area. You will see some aerials pointing towards Sudbury main , some Aldeburgh and others Woodbridge relays. Why not forget Freeview and go for FreeSat? Many more channels good reception. You'd have the expense of a dish and box but should solve reception problems.

Thanks Kevin and Robert.
Freesat seems to be the answer, but recorder box is about £250, have the dish.
That Sudbury xmitter is so frustrating, all the muxes except channel 60, Arq A.
I am on the coast, Dover gives a full service, but miss the local stuff.

Nick: What is the make and model of your receiver?

Am I right that you have said a few weeks back that others in your locality also cannot receive C60, but can pick-up C58 and C56 ?

jb38: Dover uses C59 and Nick says that it comes in strong. Do you think that the difficulty with Sudbury's C60- could be that it is offset towards Dover's C59 ?

Nick, do you receive Dover whilst having the aerial positioned towards Sudbury? There would appear to be about 90deg difference in the transmitter directions.

Dave and Kevin,
I have three boxes on three Sudbury aerials. No one box is better than the other and each one works slightly differently, reception-wise, but only because they are on different aerials. If I swap aerials, they are all the same. No aerial gets c60, except occasionally, whilst c58 is usually ok.
I also have an aerial specifically on Dover which I put on the shed to get Dover analogue to play with old tvs when Sudbury ceased analogue. When Dover went digital, I thought I would take it down----but then found it was the only way to get the full digital service!
I think re Sudbury those in authority have much to answer for. When ITV 3 was on 14 kw it was fine, now on a new channel on 100kw it comes and goes.
Having said all that, yesterday I could not even get a picture that would not break up even on c41, from Sudbury, which I put down to the Dutch, who came in with the aerial at 90 degrees to Holland.....Dover...she was fine!

Dave Lindsay: Yes, that aspect could well be a factor and especially if Dover is as strong as is reported by Nick as it could be desensitizing the tuner, although I cant help but feel that this level of reception from Dover (@ 66miles / 185 degrees) could well be short lived when the seasonal / tidal conditions change, or even maybe even before it!

Nick: Having just came on a few minutes ago I noticed your latest posting where you mention that you are using three boxes which if connected (in turn) to the same aerial all work about the same, and its this statement that makes me curious as to what brand model numbers they are? the reason I ask is because about 15 different brand names all use the same chassis and likewise all of these brands although different will all perform about the same as each other, and so I just wanted to confirm that this isn't the case with what you are using, as if they were in the multi-brand range that uses a common chassis then obviously for a any reception tests to have any level of validity then the device being used for the reception test would have to be outside of that group.

Thanks both.
The receiver on Dover is in the shed, aerial on the shed at eaves hight housewise. Tuner is Digital Vision AD BEAV. I have tried it almost daily since Dover went digital, always all channels.
In house, 3 on Sudbury. One a tiny cheapy from Tesco, name not to hand, TVOnics digital tv recorder, and the third Digilogic DSTB1000. All sd only.
