David George: Please located a group A aerial on the roof, not in the loft.
You must use a suitable aerial for DAB reception.

Hi
My postcode is EX41LP I have a new Samsung TV and I can get every channel except Film 4 which is totally unwatchable due to the picture breaking up. I have a professionally fitted Ariel directed at Stockland hill. My old TV with a freeview box has no problem.
Any Ideas

Hi
Thanks for the suggestion but I have nothing connected to my TV. I see from the data about Stockland Hill that Film 4 is only broadcast on a low power but if this is the case why have I had no problem until now ?? Very strange.

Hi,
I am in Exeter .
I have been having problems with the multiplexes on CH22 and CH28 (STOCKLAND HILL). CH22 is the worst where sometimes I've had no picture at all or a slideshow with sound stuttering. Even when it is perfectly watchable, if I'm recording a TV station, from ANY of the 5 multiplexes, the programs on multiplex CH22 start breaking up again. Any ideas as to why this is?
Also, according to www.digitaluk.co.uk/postcodechecker/, it gives a bearing of 72 degrees to Stockland Hill from my address and the website www.magnetic-declination.com/ states a magnetic decination of 2 degrees 41 minutes WEST, Declination is NEGATIVE and Inclination is 65 degress 43 minutes.
Therefore, should I be pointing my aerial at approx. 69 degrees instead of 72 and having it at an angle of approx 66 degrees from upright or, to put it another way, 24 degrees up from level?
If I'm correct, is this small adjustment likely to make a difference?
I hope this makes sense to you and I'd be glad for your input on this.
Many Thanks.

Iain Marshall: Is your aerial on the roof?
It is often best to use a signal strength meter to determine the best position for an aerial. It is, after all, the signal that matters.
The "larger" your aerial is the more directional it will be.

Thanks for getting back to me.
Aerial (Group A and about 4-5 feet in length I believe) is in the loft at the rear of the house with no other building or big trees nearby in viewable line of sight.
The signal used to be fine on ALL 5 multiplexes up until approximately a couple of months ago, I think, so it's odd that only the commercial multiplexes seem to be affected now. As I said before Mux C/Arqiva A (CH22) is the worst for me but according to digitaluk it should be the highest of the 3 commercial Muxs and have a 'Served' strength of 85 whereas MuxA/SDN (CH25) is 80 and MuxD/Arqiva B (CH28) should be the worst at 71. Surely something is amiss there? Why is this and can you confirm digitaluk's info is correct?
With me Mux C/Arqiva A (CH22) is the lowest followed by MuxD/Arqiva B (CH28) and MuxA/SDN (CH25). How come the signal strength order of the commercial Muxs that I'm receiving differ to that stated on digitaluk?. Mux1/BBC A (CH26) & Mux2/D3&4 (CH23) have the highest signal strengths and are fine 90+% of the time.
Why do the 3 commercial Muxs broadcast at a lower power compared with Mux1/BBC A (CH26) and Mux2/D3&4 (CH23)?
Why can't they ALL be the same?
Is it because of interference problems with neighbouring transmitters or is it just a case of that they can't afford the equipment necessary for a higher signal strength
Anyway, getting back to what you said in your reply (Thursday 3 February 2011 7:59AM), YES it maybe best to use a signal strength meter, but I don't have one. If I did, I'd use it.
So, PLEASE can you tell me if am I applying the given data on the websites I mentioned in my first post (Thursday 3 February 2011 4:35AM) CORREECTLY or NOT?
Have I got the correct bearing? Should I be subtracting 3 degrees to make it 69 degrees, should it be 72 as listed on digitaluk or should I be adding 3 degrees and therefore pointing my aerial at 75 degrees?
Have I got the this Inclination business correct or does that not matter?
Also, why, on the digitaluk website for stockland Hill from my address "http://www.digitaluk.co.uk/postcodechecker/main/trade/EX2+4LX/38/0/1uu98hm9f6unfhjbiqo1p42h84" are there so many changes to the signal strength of the 3 commercial Muxs (MuxA/SDN (CH25)/MuxD/Arqiva B (CH28)/MuxD/Arqiva B (CH28)) during 2012/13? Before my first post, in your reply on Wednesday 19 January 2011 8:17PM to George Baker, you stated that "the commercial multiplexes will be at the low power levels until 2012".
According to digitaluk, ALL Muxs are at the highest strength (Served) that they will ever be NOW, EXCEPT MuxD/Arqiva B (CH28) which increases from 71 to 84, but then later in 2012 following a "COM late power-up" change, MuxA/SDN (CH25), MuxD/Arqiva B (CH28), MuxD/Arqiva B (CH28) reduce from 80/85/84 to 59/58/61, then later again in 2012 to 53/53/56 and then in 2013 there are two more changes listed making them 53/52/56 then finally 53/52/55. The signal strengths of these Muxs look like they are going to get WEAKER, NOT STRONGER. Can you confirm?
I apologise for this being so very long, but I wanted to give you as much info as possible.
I would very much appreciate your input on these points.
Many thanks.

Hi Briantist,
thanks for getting back to me again, but is "Please move your aerial to the roof" ALL the advice you can give me?
Yes, I guess putting it on the roof MAY help, but unfortunately, I can't afford to pay someone just to move the aerial to that location and it's too dangerous to do it myself. I was thinking of attaching it to the outside wall of the house as high up as I can, but haven't got around to it,yet, and anyway, as far as I'm concerned, I shouldn't have to move it anyway.
ALL NEW cabling and connectors were used when the NEW AERIAL was fitted back in MAY 2009 and EVERYTHING was 100% fine up until a couple of months ago.
If everything was fine for 18 months or so, what's changed to lower the signal strength of the commercial Mux's? Has anything changed at the transmitter that www.digitaluk.co.uk have not listed? Is there a problem with the commercial Mux's that no-one seems to know anything about?
PLEASE can you just inform me as to which bearing I should be pointing my aerial and whether I've got this INCLINATION thing correct.
Even if I eventually HAVE to move my aerial outside, I will STILL need to know if I've interpreted this information CORRECTLY so I can position it properly, but before I waste time and money on moving it outside, I'd just like to check that I've got my aerial setup properly for it's current location in the loft and THEN I can decide whether or not it is actually necessary to move the aerial outside.
Many Thanks.
PS.
Could you, if you are able, PLEASE answer the other questions that I asked you?
Why do the 3 commercial Muxs broadcast at a lower power compared with Mux1/BBC A (CH26) and Mux2/D3&4 (CH23)?
Why can't they ALL be the same?
Is it because of interference problems with neighbouring transmitters or is it just a case of that they can't afford the equipment necessary for a higher signal strength?
