Are we going to be able to get digital radio in the IP 12 area? No signal here without an external aerial, whereas in IP15 it is strong. I believe the signal comes from Aldeburgh, 10 miles away or less in a straight line. Seems a rotten transmitter for DAB, whereas FM Radio Suffolk comes through well from Aldeburgh in IP12. Can't they turn the wick up?

Nick: Looking at the list of BBC National multiplex transmitters, your nearest would appear to be Aldeburgh (1.8kW), Manningtree (5kW), Mendlesham (4.3kW).

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.
