What are the aerial types about? Are they high-gain?
published on UK Free TV

See: Freeview reception - all about aerials

TV aerials are designed to receive certain groups of channels, for example a type "E" can receive on channels 35 though 68, and a "W" is a "wideband" aerial. This is different to a "high-gain" aerial. For more information can I suggest:

http://www.bbc.co.uk/reception/analogue_tv/aerials.shtml

In the UK the main transmitters require the TV aerial to have it's "fins" horizontally, relay trasmitters require the aerial to be mounted with these fins vertically.

Both the type and position of aerials are designed to give the best possible reception with the least interference, and change from place-to-place around the UK

Does the Shatton Edge transmitter broadcast all the Freeview channels? I get perfect reception on 31 channels only and cannot get ITV3, Dave, Film4 and several others. I have tried rescanning after clearing the channels

John de Carteret: You're getting everything that Shatton Edge transmits. The "missing" Freeview content you're after is only available from the Emley Moor main transmitter - Shatton Edge is a relay.

simon: You are indicated as being only 4 miles away from the Crystal Palace transmitter and as such could be suffering from the reverse of what you suspect, insomuch that rather than the signal being weak it could be on the verges of being too strong, as the symptoms seen by the viewer are "exactly" the same in both these cases.

If you can access a set top aerial, try a test using that on the channels that you were having problems with, if the situation is slightly improved then you will require a low value attenuator to be placed in line with the aerial socket on your TV.

This said taking it that you aren't located in the ground floor of a property surrounded by other tall buildings, as in that case you could be suffering from a weak signal through screening from the signal.

Hi, I have sky in the house, but have just had a converted garage put in, would like TV in there, we have got electric but nothing else. Would one of the new TV's pick up in there with an indoor aeriel? We live in the np7 8de area. I do have sky in the house but am finding it expensive now and would like to change to freeview, which I think I can do in the house as we still have an external area built in! I would be grateful for your advice. Many thanks. Julie

julie: my parents live at bn207hx and they have real problems getting a decent picture most of the time. I believe thay are directly under the eastbourn tansmitter Could they get a better signal by changing the direction of the aerial.

Geoff b: Try adding some attenuation to bring the signal level down!

The effective transmission power of the Eastbourne transmitter was increased at switchover. As they can reach out and touch it then they aren't likely to have a poor signal.

Something like this:

julie: Judging by your location I think you will only be able to receive the Public Service channels, so may be better off with Freesat.

The Llanfoist transmitter, which is to the east of the A465 is the one to which aerials appear to be directed to, according to Streetview photos. This carries BBC, ITV, ITV+1, ITV HD, ITV2, S4C, Channel 4, Channel 4+1, Channel 4 HD, Film4, More4 and Channel 5.
