Nick.Aldeburgh.As i mentioned in an earlier text to you on Monday 2 July 2012,12.44am,if you decide to opt for Dover go for it.
A good quality semi-wideband group E (brown tipped) X-Beam XB16E aerial plus copper-copper black coloured co-ax cable and brass co-ax plug will be sufficient for Dover transmissions.
Or if you prefer Aldeburgh relay then a group A aerial (red tipped) will do.

Thanks Mark,
I will give Sudbury a few days and see if it settles down, otherwise I think Tacolneston is worth a try. I understand since going digital it has a higher mast and coverage, Aldeburgh is no good, not even got ITV 3.

Please would someone explain what is meant by 'line of sight' re tv transmissions? Presumably this does not mean that with sufficient magnification we could see the transmitter. I ask as Dave kindly said from my location Dover was 66 miles, line of sight. Apart from North Kent, there is just sea between here and Dover, and the curvature of the earth means there is a huge wall of water between.
Incidentally, it was only in summer I could get good analogue from Dover, with C4 particularly unwatchable in winter, so guess I am currently getting some help to get all digital channels. In winter the signal could vary significantly minute to minute, sea mist being suggested as the cause. Thanks.

Had new high gain aerial fitted yesterday. All the channels are back. Had to do a complete new auto tune to get them back all is good now. I tried to add new channels first, no good.

Nick - Line of sight in simple terms means that you have no immediate obstruction i.e. Trees, Buildings, Ground terrain obstuctive issues that may impede the digital signal coming to your TV via your TV aerial from the transmitter. Unlike the analgue transmissions the digital transmission is precise similar to that received by satellite to a satellite dish. If you have an unobstructive clear line of sight to the tramsmitter and everything locally in terms of your aerial, connectivity etc should see you free of any recxeption issues. Satellite reception can be a little bit more problamatic in certain weather conditions extreme heavy rain or snow build up on the LNB - the item that's seen on the end of the dish boom arm. In this scenario it's a case of usually a brief or interrupted signal signal.

Thanks Les, but what about all that sea? I can't see beyond a few miles from my upstairs window which overlooks Dover, theoretically, nor can my aerial, because of the curvature of the earth giving me 60 odd miles of deep water in the way.

Why is it that the info, top, is out of date re xmitter power/frequencies, yet there is a seemingly current message about xmitter works?
On the other page about Sudbury switchover it says xmitter works from 18 June for a week, so how do we know if they have finished?

Nick,Aldeburgh.Oddly enough i did mention in my text on Wednesday 27 June 2012,1.40pm then on my hols in St Annes on Sea,Lancashire in my first paragraph that the Sudbury page requires updating due to the COM multiplexes increasing in strength to 100kw apiece,albeit i forgot to mention the change in frequencies back then.
Im sure Briantist the owner of this ever valuable and useful website will ultimately update this page in due course once he catches up with the Sudbury pages,after all he is a very busy man assisting us all.

Nick - The sea shouldn't make any difference it's the transmitter coverage - whether it's a main or relay transmitter and their respective outputs. In most cases an existing aerial should suffice, but if your on the fringes of a transmitter(s) you may well need to consider if a particular aerial, cabling etc is up to the job. Alternaitvely as in my area Low Powered Relay transmitters and ground terrain and obstruction issues often dictate the installation of "Freesat" service over "Freeview".
