Cain: When the power increases at Stockland Hill on 18th April 2012 it is possible that you might be able to receive the COM muxes direct from Stockland Hill using a good quality group "A" aerial mounted for horizontal polarisation. There are no plans by the mux owners to install additional equipment to add these muxes to the Exeter St Thomas relay due to the extra cost involved. With regard to the regions shown by ITV1 HD (and ITV1+1), this again is down to equipment costs, but no doubt in due course each region will eventually be converted to HD and also have the correct version of ITV1+1.

Aerial positioned for Stockland Hill, Devon. Started having problems just before Christmas. Pixellation mild to severe and some channels dropping out completely. Replaced the booster splitter but still having problems mainly with multiplex 4. Help, please.

tony: If by full you are meaning the commercial muxes as well then its likely that you are picking them up from Stockland Hill @ 23mls / 47 degrees.
You should try swinging your aerial around to Beacon Hill @ 11mls / 213 degrees as its also a full service transmitter, but its all total hit and miss though, and as you will obviously realise you are virtually next door to your local Dawlish PSB only transmitter.
To save yourself confusion, you should first of all scrub the channels you have already stored by carrying out a factory reset, then manually tune in Beacon Hill on the following:- Ch60 (BBC1) - Ch53 (ITV1) - Ch57 (HD) - Ch42 (SDN) - Ch45 (ArqA) - Ch51 (ArqB)

Hello.
I live in the EX4 1SB postcode and am having an awful time with my TV signal. We have an external aerial, close to 25 years old which as far as I know has never moved from the time it was installed. We can't be more than a mile or so from the St Thomas transmitter and being as high up as we are I don't think line of sight is a problem. We can get some channels perfectly fine, like BBC1/2 or ITV1. Anything more exotic, like Dave or Film4, is either not found in a scan or is completely unwatchable when it is. I'm really just looking for some advice. Should I be trying to realign my aerial? Or even looking to replace it?
While I am quite technically minded, I have to confess that TV transmitters and signals are not really my thing.
Any help or advice would be greatly appreciated.

Mark H: The thing is that St Thomas only relays the Public Service Broadcaster (PSB) channels which are BBC, ITV1, ITV2, C4, E4, More4, C5, HD services and some others.
So if you have these perfectly then your receiver is tuned correctly (i.e. to the signals coming from the transmitter to which your aerial faces).
The best commercial (COM) channels it will find are probably Stockland Hill, and hence why reception is poor.
For an explanation of why St Thomas doesn't relay the COMs, see here:
Will there ever be more services on the Freeview Light transmitters? | ukfree.tv - independent free digital TV advice
Whether you can receive a stable signal from Stockland Hill with a suitable aerial is another question. Obviously from a signal strength point of view, St Thomas is probably the one to go for.
You might be high enough to get a signal from Stockland Hill. See here for a plot of the terrain. You have or aren't far off line of sight with it:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
Be aware the COMs from Stockland Hill are at lower power than the PSBs so if you can't get the (weaker) COMs from it, then there's no benefit in moving away from St Thomas.
Until 18th April they are at 10kW when they will be increase to their final power of 25kW. The PSBs are at their final power now which is 50kW.
It might be best to wait until the power increase in April to get another aerial.

Dave Lindsay, Mark H: While the COM muxes at Stockland Hill will increase to final power in April, the prediction for Mark H actually goes down slightly. This is because Rowridge will be using the same frequencies at high power, from the same date. They are actually going to be using the same frequencies for the same services, but the transmitters are too far apart to use Single Frequency Network techniques, so they will just interfere with each other. (Crystal Palace will also be a problem, to a lesser extent.)
The likelihood is that for a number of people in your postcode, the COM multiplexes will be unreliable for some of the time. Careful siting of the aerial may find a reliable location - it's best to get an experienced installer to do this.

Mike Dimmick, Mark H: Rowridge will be transmitting its COMs in both polarisations, but the horizontal ones will be at 50kW whereas the verticals will be 200kW, same as its PSBs in both polarisations.
From Rowridge, only Ch22 has an offset and it is positive.
All the Stockland Hill COMs have negative offsets, which probably explains why Ch22- from Stockland is predicted as being better than the other two.

Dave Lindsay: I am actually at one of the highest points in Exeter with a clear line of sight to pretty much everything in the area.
Last night I decided to conduct a small experiment, I disconnected the large external aerial and plugged in a small internal aerial, just to see what would happen. I rescanned and got all the channels I had been missing, including Dave etc. I then plugged the exterior aerial back in, recanned and of course they were gone again.
Now, with this in mind, conventional wisdom says "just use that aerial then" which is fine, for my television, but when the very same aerial was plugged into a TV at the other side of the house, there were almost no channels found. With this in mind, it seems to be that the best course of action is to go up a ladder and try to realign the aerial.
Would you agree?
