The symbol shows the location of the Whitehawk Hill (Brighton and Hove, England) transmitter which serves 96,000 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.

Dave.Thank you.That LBN figure has a red graphic included. What does that represent?Is the whole diagram a general diagram. I could not find a UK reference to LBN in Google? I assume that transmitters will have their own characteristics, and, therefore, vary.Clicking on LBN does not lead to whatever LBN signifies.

anon: The red graphic indicates the magnitude of radiation in each direction. If it had been omnidirectional (the same in all 360 degrees) then it would have been circular, for example.
At 290 to 295 degrees, the signal is at its full effective power (400W). Between 280 and 285, and 300 and 305 it is -2dB, so the power is 2dB down from (less than) 400W. Decibels (dBs) are logarithmic and not linear. For every -3dB the power halves. For example, between 310 and 315 degrees the power is 6dB down which equates to 100W.
"LBN" is what this website uses to mean "Local Brighton" multiplex. Digital UK refers to it as "L-BTN".

Aerial on roof pointing at Whitehawk transmitter
Have followed Freeview reset procedure. No signal reported on BBC1 or BBC2. Can get BBC1 HD and BBC2 HD on 101, and 102. Can't receive any BBC4 or BBC radio channels.
Have tried partial scan, by inserting aerial after 50%. Signal picked up BBC1 and BBC2 on channels 1 and 2 but reception very poor.
Any advice please.

Jim: BBC standard definition TV and radio are carried on PSB1 multiplex. Whitehawk broadcasts this on UHF channel 60, which is the highest and the closest to 4G services in the 800MHz band which may be operating in your area, these occupying channel 61 upwards. Therefore, it's worth seeing if 800MHz 4G has started by ringing at800.
at800 is the company set-up by the mobile operators and tasked with alleviation of reception issues:

Currently in process of obtaining equipment prices for a new wall mounted aerial removing the existing from the stack on our bungalow.
I'm told Brightons Whitehawk hill is a better transmitter than Rowbridge I.o.Wight which the current aerial faces and on nice sunny days loose the signal some digital channels, one in particular is channel 64.
I've also read that the Diy sold aerial cable in not very good quality.
Any suggestions on type of aerial and cable welcome will look back in for responses if any. I'm in Worthing.

Bob: Digital broadcasts are transmitted in multiplexes ("muxes"), each of which is a single signal which carries multiple services. E.g. PSB1 multiplex carries all BBC standard definition TV and radio. Digital UK publishes a full list of Freeview services including multiplex they are carried on here:
Digital UK Industry - Channel listings
As this is a reception issue, it's therefore more relevant to talk in terms of multiplex. So logical channel number (LCN) 64 is carried on COM6 (or Arq B) multiplex.
The PSB (Public Service Broadcaster) channels have the same coverage as the former four-channel analogues. COM4, COM5 and COM6 are available from 81 of the larger transmitters.
Rowridge is unique as far as a main station goes as it broadcasts with vertical polarisation (as well as horizontal polarisation). From April 2012 COM4, COM5 and COM6 began broadcasting with a power of 50kW horizontally and 200kW vertically. The PSBs are 200kW horizontally and vertically. Thus, you might find that vertical polarisation solves your problem.
DIY aerials tend to be widebands. All of Rowridge's channels are Group A, as they were for analogue. Thus, aerials installed for former four-channel analogue should generally be suitable for all reception of all channels. Wideband yagi aerials aren't as good on Group A channels so a Group A aerial should be used. See:
Rowridge Transmitter
While log periodics are usually wideband, to the best of my knowledge there's one exception; this one made by Vision:
V20A2 20 Element Log Periodic Group A Aerial ? Vision Products - Powerful Products. Easy Installation. Excellent Value
There's another point to be aware of and that is the new quasi-national HD muxes, COM7 and COM8. Rowridge carries these horizontally only and Whitehawk doesn't carry them at all. So if you can get them from Rowridge then switching to vertical polarisation will forfeit any chance of reliable reception of them.
Rowridge broadcasts BBC South and ITV Meridian (South Coast). Whitehawk carries BBC South East and ITV Meridian (South Coast). So choice of transmitter dictates BBC region but not ITV region.
The transmission power of Whitehawk effectively increased at switchover. The Findon relay had a considerable boost in power but only carries PSB channels, it being a relay of Rowridge.

Bob: I should add that in order to understand Digital UK's list and its multiplexes:
PSB1 = BBC A
PSB2 = D3&4
PSB3 = BBC B
COM4 = SDN
COM5 = Arq A
COM6 = Arq B

Bob : In addition to, but apart from that said by Dave Lindsay, the question of which is the best station to use for reception is entirely dependant on your location within the Worthing area, as wide variations were found in DUK's predictions for reception between a couple of post codes used for test purposes, Whitehawk Hill being far in a way best for reception in the DN14 area, whereas not in the DN11 areas, none of the stations predicting good reception in that area with the exception of Rowridges PSB channels on vertical polarity.
Therefore, I suggest that the best policy would be to enter your post code into the reception predictor referred to and study the results. (Link for below)
Another point to note regarding aerials, as you are intending to mount the aerial on a wall bracket, then be aware that not all aerials lend themselves to being mounted on such brackets close to a wall, this being where log periodic aerials score, as they, in most cases can, and of course are ideal for reception of the channels used by Whitehawk Hill, (excl Vision V20 A2 20) that is should you reside anywhere in, or near to the BN14 area.

Isn't channel 54 from the the Saltdean transmitter?
I can't receive any of the LBN channels?

Ken: No, as although Mux C54 is used by both Whitehawk Hill and the Saltdean relay, they do not serve the same purpose, C54 (LBN) on Whitehawk Hill being a local "commercial" Mux beamed towards the Brighton area, whereas C54 on the Saltdean transmitter is one of the three PSB (only) transmitters used by that Freeview "light" relay station, i.e: does not transmit commercial (only) programmes.
