The symbol shows the location of the Heathfield (East Sussex, England) transmitter which serves 170,000 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.

Is the transmitter output the same in all directions?
Radiation patterns withheldSaturday, 16 June 2012
Dave H: One further thing. It's always worth checking that a receiver has tuned to the desired transmitter and that you aren't looking at the output of another transmitter.
For Heathfield they are:
PSB1=C52
PSB2=C49
PSB3=C47 (HD mux)
COM4=C48 (to move to C42 on 27th June)
COM5=C44
COM6=C41
The information at the top of this page which says that COM4 is now on C42+ at 20kW is incorrect.
Check the signal strength screen whilst on one service on each of these multiplexes. The first one on each are BBC One, ITV1, BBC One HD, ITV3, Pick TV and Yesterday. (Refer to the DMOL page of multiplexes I gave you.).

Dave - many thanks for your very detailed feedback...I'll check that we're tuning to the right channels for Heathfield (although I'm pretty sure we are) then remove the boosters and see how we get on. Thanks again.

FAO Dave Lindsay.
Thanks for the reply Dave. I live in Trevelyan Place, heath Road. It's a development of flats built by Barratt 2000-01.
Prior to switchover, yes I had all freeview channels with no recpetion problems.
I don't think we've had the aerial replaced.
Yes, it's communal (ie. flats).
I look forward to your response.
Cheers

stuart smith: Communal aerial systems are sometimes filtered to only allow channels that are used through (or only allow group(s) of channels through).
Look at the table above, under the heading "Transmission frequencies". Accepting that there is an error which says that SDN is currently on 42+ when it is on 48. On 27th it will move to C42.
You will note that prior to switchover, with the exception of 29 and 34, the lowest channel was 47.
A filter that cuts off at one channel won't have an absolute cut-off where one channel gets through unscathed and the other gets attenuated completely. It may reduce a neighbouring channel a bit. So perhaps up to C39 or C40 is filtered which is why 41 is not good.
You "may" see some affect on 42 when it comes on air, if it is the aerial system that is the cause of the problem, and if it hasn't been rectified by then.
You need to establish, as firmly as you can, that the problem lies with the aerial system and not your equipment. If you have more than one TV or box, then try each in turn. When trying the TV, connect the aerial lead from the wall directly to the TV and not via a box, so as to discount the box as being the source of the problem.
On each receiver, assess the signal strength of each multiplex and compare, perhaps writing each down. Different receivers have different scales and tolerances, so don't compare a single multiplex between receivers; only compare all multiplexes on each receiver. See if 41 is down relative to the other muxes with all receivers. Obviously 48 is expected to be lower then the others.

Message to Dave Lindsay from Keith Myers. Thanks for your reply. My location is RH2 (Reigate). We are the wrong side of the Hill to receive pictures from the Reigate transmitter hence we use Heathfield. As I said good reception before the switchover poor afterwards (BBC and ITV).

Just to sign off on my string for the benefit of anyone in the same position as me - Dave; you were absolutely right...the booster was the problem and all channels are now fine (including QVC, but then you can't have everything). Thanks again for your help.

Keith Myres: If I am right in suspecting that you are served by a communal aerial, then I suggest that the problem might be that its amplifier needs turning down because it is boosting the signal too much.
This could be the case because the signal going into the aerial is now stronger than it was and hence the signal coming out from the outputs must be so as well. This could be above the level that receivers are built to accept and therefore the cause of your problem.

Dave H: Good to hear you got it fixed, and a simple fix at that.

stuart smith: 41 is the only frequency that is suffering from poor signal strenght and quality. I have restested each piece of equipment individually. Results are consistent.
Thanks

stuart smith: This suggests that it is a problem with the aerial system and that it needs adjustment following switchover.
It may be helpful if you can find any neighbours with the same problem.
