Hi Noman,
PC/Wireless Lan interference could well be part of the problem. However, the area I live in seems to have lots of wireless signals coming from what appears to be every direction. I use wireless in my home too, and wherever I position my PC/USB Wireless Adapter and Modem/Router, I get several other Wireless Routers/Access points showing up. So, for this reason alone, I think moving my aerial around the loft is unlikely to help.
If other wireless devices are possibly causing interference, then this is only likely to get worse over time as more and more people use devices that require wireless networking/Internet access. Having said that, TV signals are in the MHz (Megahertz) spectrum (Stockland hill ranges from 481.8 to 538.2MHz) whereas wireless computing usually uses the GHz (Gigahertz) spectrum (2.4GHz or occasionally 5GHz) so, I don't believe that they should cause any conflicts, but I could be wrong on that.
Also due to my location and neighbouring houses, (I live in terraced road), moving the aerial elsewhere in the loft is not practical as I would be introducing many walls between the aerial and the outside world. Currently, I only have my own slate roof in the way.
Pointing my aerial directly though a wall instead if the roof is not possible either because the nearest outside wall is almost parallel to the direction that I need to point the aerial. The next house in the terrace gets in the away again too if I were to try a different wall.
I believe that I currently have my aerial in the optimum place that I can put a loft mounted aerial. That's why I put it there in the first place.
Anyway, Noman, thanks for your advice. It may not help me, but it may help someone else.

Hi Brian and Phil Wallace,
I've just found the following document at:--
http://www.digitaluk.co.u….pdf
On page 3 it says that the www.digitaluk.co.uk postcode checker, not only provides customers with information, but also provides installers with:
UHF Frequency channels used through switchover and beyond.
Required aerial groups.
Transmission powers for pre and post switchover.
Compass bearing direction and distance from address to transmitter.
It's that last point that caught my eye "Compass bearing".
If that is how they list the bearings, neither I nor Phil Wallace need to correct the bearings stated. I should still use 72° and he 248°.
Just thought I'd let you, Phil and anybody else know that the bearings stated are Compass bearings and not map bearings so no adjustment is needed.

Iain Marshall: Except of course I wrote the code for this site and my code on the site works out the baring shown here and I can tell you I wrote them as grid bearings.

Hi Brian,
So, I SHOULD use 69° and NOT 72° after all then!
It is, obviously, a bit confusing when you see the same bearings listed on two independant sites and one says compass bearing and the other a grid/map reference.
Perhaps someone, probably best if it was you, could let digitaluk know that, despite them having the same bearings listed as you do, their bearings are ALSO grid/map bearings and NOT Compass bearings.
They should then, therefore, inform people of this fact and give instructions to people as to how to work out the Magnetic Declination for their location and how they should apply it, or, change all of their bearings to include Magnetic Declination. I guess that it would be easier to do the former as I doubt the whole of the UK has a 3° difference, as I do, and even if they did, they might have to add it on instead of subtracting it.
Anyway, I'm inclined to accept your information rather than digitaluk's now.
Thanks for the clarification.

Iain Marshall: the aerial has basically a cone of acceptance and that cone is wider than 3°. Particularly with loft installations, you frequently have to move the aerial away from line of sight to avoid, or at least reduce, picking up reflections anyway. It doesn't matter all that much. Just move the aerial to the place where it produces the best results.
You can see some diagrams of the actual polar response of typical aerials at Aerial Polar Reponse Diagrams .
Professional installers should be using equipment that shows the Modulation Error Ratio - how far the actual received phase and relative signal strength are from the ideal. Higher numbers are better. For example, the PROMAX TVHUNTER -http://www.dastv.co.uk/shop/Promax_TV_Hunter_Terrestrial_Meter_2423.php . Unfortunately the price of this equipment puts it outside the range of the DIY installer.

Hello my name is Mike and I have just had BT Vision+ installed and they told me I would have 70 channels including the High Definition channels. I have bought a high definition telly and a high definition cable and have made the box search for channels but it only finds 18 channels and none of them are in high definition. I do have a good aerial and the BT chap did all the installing.
Please can you tell me what I am doing wrong? I am not at all technically minded, it took me days to work out how to record the tv and then even more days to find out how to play back what I had recorded.
Any help would be very greatly received, I live in postcode area EX4 Exeter.
Thank you.

Iain,
Further to my earlier comments, interference from wireless lans are not caused by the radio link itself, but data and processor noise radiating from the lan and it's associated wiring. The problem is normally very localised.
Another comment I'd like to make is that loft mounted aerials tend to suffer multipath signal problems considerably more than roof mounted ones. Aligning your aerial directly onto SH is therefore not the complete answer, you need to position it for minimum error rate (Picture errors) which can be +/- 15 degrees from the 72 degrees you had calculated. As you're in a reasonable signal strength area for SH, it's worth giving it a try. The ultimate solution is to save you pennies and get the aerial fitted to the chimney on the roof. You could also consider freesat.

Help, I am living immediately down the hill from the Bakers Hill transmitter. My query is why can friends in Tiverton get Channels 19 + 36 and I am unable to? I am obviously using an ariel, would I receive all of these lost channels if I bought a Freesat box

Alan Haley: We really need a postcode to be able to answer your question sensibly.
From what you've said, it's most likely that you're using the Tiverton relay transmitter, which does not transmit the commercial multiplexes that those two channels (Dave and Create & Craft?) are carried on. The commercial multiplex operators were offered, and refused, the opportunity to extend their services to the relay transmitters. They don't consider it cost-effective - it would probably double their transmission costs.
People in other parts of Tiverton might be able to use the main Stockland Hill transmitter, which does transmit the commercial multiplexes as it carried them before switchover. Even a matter of a few feet can have significant effects on reception, which is why we need the full postcode. Ideally, the house number as well. Digital UK do predictions for the 100m square that your house, or the centre of your postcode, is in.
It may be that you can't yet get the commercial multiplexes from Stockland Hill, but - depending on where you are - you might be able to after switchover is complete. The power of the commercial multiplexes will be increased some time (after March) in 2012.
Dave is not on Freesat. Currently you have to have a Sky subscription. The transmissions are scrambled to prevent reception outside the UK, and the channel gets kickbacks from Sky subscription income. Dave is in the Variety Pack.
