Stuart O.: Refer to the Digital Terrestrial Broadcasting Stations for Multiplex Licences Version 7 27 January 2012:
http://licensing.ofcom.or….pdf
For Moel y Parc, 51 (SDN) and 52 (ArqA) are 10kW. 48 (ArqB) is also 10kW but "Until 24 October 2012, services are subject to a
reactive power restriction of 5,000 Watts".

Stuart O.: Perhaps both is correct. From Fenton, the Commercial multiplexes are at half power with respect to the Public Service ones.
If you go to the plot on the Fenton TV transmitter page (the one at the top of this page), you can select the different multiplexes and see their expected coverage.
The page Find out how to receive Freeview and Freeview HD | ukfree.tv - independent free digital TV advice only shows those that have the greatest coverage. (LL115FQ)

Jon Stanley: Assuming that you are receiving from Mendip, then wait until 28th March when Arqiva B multiplex which carries Sky Sports will go to full power.

ATOMS: The Commercial broadcasters do not wish to spend money on transmitting from some 1000 or so small relay sites such as Haslemere.
Digital UK Tradeview doesn't rate Midhurst at your location at all, not even "poor". I think that the fact that there is a hill in that direction means that you're not going to get it.
The next best transmitter, which is shown as "good" is Crystal Palace, but unfortunately the Commercial (COM) channels (which Haslemere doesn't transmit) are co-channel.
The only other suggested possibility is Hannington, but its COMs are shown as "poor" and their transmission power is half of its power for the Public Service channels (which are "variable").

Tony: With a more exact location I could perhaps be more specific.
But taking the post code LL11 5UN and inputting it in the Digital UK Tradeview predictor gives:
Postcode Checker - Trade View
There are a number of transmitters found. The only Welsh one is Moel y Parc, but Sutton Coldfield comes up tops.
Unfortunately, BBC A (standard definition services of BBC One, BBC Two etc) and BBC B (HD services) are co-channel (same frequency) with those of Commercial services from Sutton Coldfield.
This means that you will only be able to pick up ITV Wales and S4C until 2013 when they too will be co-channel with Sutton Coldfield. This is unless there is somewhere your aerial can be mounted where the signal from Sutton Coldfield can be blocked such as on one side of your house (not sure how effective this might be).
As I say, with a more accurate location I might be able to be more specific, but based on what I found, the Sutton Coldfield would appear to be the spanner in the works. (GU273RW)

Dave Williams: I think that Winter Hill is your only possibility of receiving Granada/North West TV. If you are looking at DIYing, then I recommend that you look at ATV Sheffield's website. It's full of lots of information and they sell stuff mail order.
This page is what they recommend for Winter Hill: Winter Hill Transmitter (LL115UN)

sophie, tracey: It seems that the weather is playing its part, signals are carrying much further than they normally and interfering or obliterating reception of local services.
See here for an explanation:

Sophie: Assuming that you receive your TV from Rowridge on the Isle of Wight, run the aerial scan and unplug the aerial when it gets to 20%. This will allow you to pick up Rowridge's frequencies. If the French signals are coming in on higher frequencies, you should miss them out. If they are around those of Rowridge, then there's not a lot you can do but wait. (LL115UN)

Clive: It's probably the lift conditions that are making signals travel further than they normally would. See here:

We've had a report of French TV being received in Portsmouth and signals from Mendip in Somerset being picked up in Rayleigh.
I say "probably", it may be advisable to check that your receiver has tuned to Whitehawk and not Rowridge or one of the other transmitters in the area.

trevor: The Commercial multiplexes are at low power and restricted in the general direction of Guildford due to being co-channel with some of its services. The Public Service multiplexes are not.
