In the east ipswich area signal is very weak and only a roof top Ariel will do, My question is will there be any relay transmitters set up for a stronger signal.

TERENCE COOK: The UK transmitter network was always designed to be received with a rooftop aerial. There are no known plans to build any new transmitters to provide new coverage (there are a few being built to replace coverage that will be lost from changes taking place at existing main transmitters, but none are planned for Suffolk).

nick horrex:

If you have several weeks to spare, I'll try to explain it for you. Having worked in the TV industry since 1960 until retirement I have had to deal with many types of aerials. The explanation involves complex physics and only as I studied for my Masters Degree did I realise just how complex aerials are.

Mike P
they are indeed, but if you get time to explain how extra reflectors on the log periodic are beneficial, at your leisure, it would be appreciated.

It seems to me that freeview is a rather naff setup. I am technically in the Aldeburgh transmitter area, but want more channels. I had a group B aerial which was fine for Sudbury on analogue, including the weak signal then from C5.

This was no use when freeview came along. After much experimenting I built the present aerial. It got me all the muxes, including the worst one on channel 60. I get 90% plus on all muxes, strength and quality. But regularly several get knocked out, though the ones on ch 41 and 44 are the last to disappear. When any/all disappear, the aforementioned figures go down to zero. It seems that anything it does not like, rain, fog, hot sun, Dutchmen, knock it out at the drop of a hat! There are no half measures, it is all or nothing.

Can somebody help, please?

Since the bad weather I have been unable to receive the independnt channels (C4/ITV/C5/etc)

I have retuned, checked the aerial, in fact, done all I can but, nothing but pixelation!

Steve: The weather might have caused water to get into the system, etc. Check all connections and cables , and if your signal is still too low (check it), then you might have to call out a professional.

My postcode is Co100rj. I regularly get channel drop-outs - usually on ch 37 etc. On Sunday 18th March ch 18,19,22,25,31,35,39,42 and 47 were unwatchable. The next day all worked fine. Often l find that it is a group of commercial or bbc channels that have trouble- multiplex? I have also experienced intermittentnoise? I wondered if a transmitter was nearby?
Any comments?

Rupert Allen : You're just 6km from the Sudbury transmitter and should be getting a strong signal, possibly too strong which can overload the tuner. Search for the article titled "Too much of a good thing" on this website and try an attenuator.
