The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Crystal Palace (Greater London, England) mast?

I am still managing with my old aerial (band A?) pointing at Sandy Heath, the recommended transmitter for my location (Knebworth), and get a good signal for the main channels but don't always get C48, C51, C52 stuff. Recently I have discovered I am recieving C22 stations (eg Movie Mix) (variable strength). Is this from Crystal Palace (???!!!) I wonder ? In which case it would surely indicate that my best bet is simply to turn my aerial around to point at Crystal Palace. Any thoughts ?

John V Osborne: If you aren't bothered about which regional programming you get then go with the tranmsitter that gives you the best reception.
You may get improved reception from Sandy Heath with an aerial that is more sensitive on 48, 51 and 52 - this being a wideband or even probably a Group K.

With your current aerial being a Group A one, then it is probably only suitable for receiving all channels from Crystal Palace, and as such rotating it might be your best bet.

Thank you. I have just tried manually tuning my set to C23 although a weak signal it has found all stations !!! Must be Crystal Palace despite being on the edge of their transmission range and my aerial pointing in the opposite direction ! Hate to think what will happen if I now do auto tuning ???
Cheers JVO

John V Osborne: Judging by the fact that there are houses with aerials pointing at either transmitter, and in some cases an aerial on each, and looking at the size of those aerials I suggest that perhaps reception from each is about the same.
You don't have line-of-sight to either because you live in a dip. This is probably the reason for higher gain aerials, as at 30 miles from Crystal Palace you aren't that far away, considering its power.
You may find that reception from Crystal Palace varies over time because your aerial is facing the wrong way.
If you are able to pick up the PSB channels from Sandy Heath well with your Group A aerial then perhaps you would be able to pick up the COMs with a suitable aerial.

John V Osborne: Just in addition to that said by Dave Lindsay, insomuch that as you are located in an almost perfect position for reception of these two stations via both ends of the aerial (only 2 degrees out), then provided that Crystal Palace is "not" being received via its signal being bounced back onto the front of the Sandy facing aerial from some distant object between Sandy and you I would say that its probably worth while swinging your aerial around 180 degrees.
My reason for saying this being, that when a signal is being received on the rear of an aerial the reflector is partially blocking the signal from reaching the active element, and of course with this being coupled to the fact that the aerial is performing almost exactly as would a rabbit ears set top aerial if positioned in the same spot by the fact that there aren't any directors to focus the signal onto the active element.

Hi there just want abit of advice... I have very old wideband aerial which ia 20 years old... I want to know will i be better off with a proper group A for Crystal Palace transmitter... I am in RG8 8DB (51.4816,-1.0490)

Rob: Yes, up to a point anyway although for future proofing a "K" group aerial is preferable, the reason being that should COM8 transpire it will be using Ch35 and although a group "A" aerial's upper limit is Ch37, which obviously covers Ch35, in reality its generally found that most of these dedicated group aerials has a tapering off in efficiency starting a few channels before the extent of their published coverage range.

Rob: Having had further thoughts on your situation and triggered by the fact that you are located at approximately 42 miles away from the transmitter, I think it best NOT to make any allowances for the proposed COM7/8 on Ch's 33 & 35 and stick by the maximum efficiency of using a group "A" aerial.
I say this based on the fact that you might not be able to receive these COM's anyway when taking your location into account as well as the coverage range expected from whats expected to be relatively low powered transmitters used for the purpose of operating as a single frequency network along with Reigate and Guildford.
Just a little point concerning the aerial presently used, I realise that you stated it being a wideband type wideband but are you positive about that? if you have a pair of binoculars kicking around have a look up the very front of the aerial and note if you see a red plastic plug on the end of the horizontal cross boom that holds the elements, if you do then its already a group "A" aerial.

Rob: I bow to jb38's judgement here as he is the professional and I'm not, but the Group A gain curves published by ATV suggest that C37 may have a higher gain than C21:

thanks to Jb38.. Yes the old aerial has black ends i have seen red ends in the neighbour hood... i saw a few triax 52's and blake high gain aerials with red ends for Crystal palace. seems to be alot black ends pointing for oxford and hannington. I only asked as widebands are pretty poor at the lower end gains... so thats why i asked about getting group A. many thanks guys.. just got to decide triax or blake? which one eh? thank you
