But the Sudbury one is the one we have always had, on which 95% of aerials are directed and by far the strongest.

Thanks whoever runs this site.

Due to the wife recording so much rubbish at the same time on sky and then going to bed I thought I would see what was on film4 via Freeview tonight. To my surprise I no longer had it. Half an hour of Google-fu later and this is the only place that I can find any information on why.

Personally I think the situation is disgusting.

Anyway a question. Would getting a wide band aerial make a difference to the signal I receive? How do I tell if I already have a wide band aerial?

I should add that as far as I am aware I had all Freeview (including HD) channels once they turned of the analogue signal but only a view (if any) before, and that I am in the CO4 area.

Thanks for any help.

Wherever the DAB signal comes from, it does not reach IP12.

Kraig: Its very doubtful if it would (if you dont already have one) as the multiplex that Film 4 uses is temporarily on very low power and numerous people located at about your distance from the station (9 mls) and up to about 15 mls are having problems trying to receive it, basically due to their tuners being slightly desensitized by the massive differential in power between the main BBC mux on 100kw compared to the 2.2Kw used by ArqB(film 4 etc).

There isnt really anything you can do about it at present, as the situation will be rectified come June 27th when the low powered multiplexes go over to high power operation.

Kraig.The answer to your question is if your aerial is tipped black on its ends then it is a group W wideband aerial,if it is tipped brown on its ends then it is a group E semi-wideband aerial optimised for the middle-upper bandwidth between frequencies 35-68/9.

Mike: I must point out that the multiplex that carries Film 4, ITV4 and others is on low power until 27th June from Sudbury. Therefore, it is likely that the problem will rectify itself then (if not before) and therefore that any remedial work (and expense) will be to provide reception of those channels between now and 27th June.

What has probably happened is that the level of the signal has dropped slightly, putting it below the threshold that your receiver needs to resolve a picture. You will need to keep manually tuning to channel 63 until it comes back.

Had you not carried out a rescan, you could have simply switched over to one of the affected programme channels to see whether they are back. In circumstances such as yours, the outcome of rescanning usually only serves to loose the programme channels from the receiver's memory.

Where a signal is below the level at which the receiver will work, retuning won't make any positive difference. If the signal level increased a little to produce a picture, it would do it irrespective of the retuning and if it didn't, then you loose it from the listings.

For Sudbury, there is no need to retune until 27th June, it will not achieve anything.
