How do I align my aerial in Aldeburgh to get the Sudbury transmitter? I believe whichever way I turn it, a meter will log on to Aldeburgh instead.

Why does a non hd freeview box not show the channels used for hd, albeit not in HD?

In Aldeburgh I would like to align my aerial to Sudbury to get more channels, but understand the meter would simply log me on to Aldeburgh because of its strength. How do I align to Sudbury please? It was easy with analogue, just turned for the best picture.

@Nick - signal meters don't 'log on' and turning the aerial to point to Sudbury should be sufficient.

You will need to to rotate your aerial so that the wire elements are horizontal because Aldeburgh is a repeater a Sudbury is a master transmitter.

Nick: "Why does a non hd freeview box not show the channels used for hd, albeit not in HD?"

Because the HD signals are transmitted with a new modulation standard, DVB-T2. A regular DVB-T box simply cannot understand the data stream that's transmitted, it just sees it as very loud noise.

"How do I align to Sudbury please?"

Cheap meters simply show a raw signal strength across the entire UHF band. These are basically useless. You'd be better off selecting the manual tuning screen on a Freeview box, telling it to tune in a known frequency (e.g. C44) and watching the strength meter on the tuning screen. That assumes the box shows the strength/quality on a specific channel before actually tuning it.

Proper meters allow you to select the channel to monitor. Professional equipment does a full decode and recode of the signal, comparing the actual received signal and the ideal to get a quantity known as the Modulation Error Ratio. The aerial should be positioned to get the best MER. However, equipment that does this is quite expensive: the Promax TV Hunter, which is fairly basic, is over £400.

Unfortunately most Freeview boxes have a pointless quality meter, showing the number of uncorrectable errors. You need to know how many errors are being corrected and optimize for the fewest errors, as this will give the most chance of reliable reception in adverse weather conditions.

Nick: Unless you changed the aerial for a wideband at some point in the past, you should do so now. An aerial erected for Aldeburgh would be a Group A aerial, designed for C21-C37, whereas Sudbury requires a Group E or wideband designed for at least C35-C68. A wideband is recommended to ensure that you can still pick up the COMs in the future: it's looking like they will have to move again to release even more spectrum for mobile phones.

Thank you Mike for very full answers. I think I will have to do it the hard way, with someone on the ground, and hope for the best.
The aerial is home-made. One of my hobbies, and tested on analogue when I could see the difference as I added directors. I don't like wideband as they tail off so much at either end, and with Sudbury in the mid band, I prefer an aerial for that group, and hope for the best with channels outside it. In essence it is an old J Beam, with the square slot dipole and reflector, but modified now with 2 extra sets of directors, tribeam

We have just switched over in North Kent and I cannot pick any signal up. I've tried a different box, switched the booster in and out and I'm using a brand new wide bad aerial which I've been waving around like a ship in a storm and still nothing. I've called the set-top box makers, Digital TV helpline and tuned manually to 5 differnet frequencies and still nothing. Basically, it f**ked. All I'm being told is to spend more money, either on new equipment or getting an 'expert' round to help me. Can anyone help???

russ grooms: Its not really possible for anyone to be able to assist without knowledge of your location (pref: post code or one nearby) as the signal levels expected at your location from the various transmitters involved cannot be assessed.

Thanks Norm, but I think I will get the Aldeburgh transmitter whichever way I point the aerial because it is so strong, and apparently the meter cannot be set to look for a particular set of channels.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
