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?
CRYSTAL PALACE transmitter - AM: Radio 4 on MW has now closed. Please retune to FM, Digital Radio, digital TV, BBC Sounds or smart speakers to continue listening. More information can be found on the front page of this Reception Advice website. from 15 Apr 00:00. .

Stuart Tanner: Yes, the signal will be stronger in April.
Switchover happens in two stages:
1. On 4th April BBC Two analogue will be switched off and BBC standard definition digital services will go on their full (post-switchover) power.
2. Two weeks later on 18th April the other analogue channels are switched off and the rest of the digital channels go on full power.
The strength of the signal isn't that important. So long as it is strong enough to produce a stable picture, then that is sufficient.
To try and get ITV1, C4 etc, go to manual tuning in the menu and tune to Ch22.

Thank you Dave Lindsay for your fast reply.
Well that puts my mind at rest i will leave the aerial as is and await april.
i cant seem to do a manual tune on my brand new goodmans freeview + box only automatic tuning lol.
I'm getting 60% signal and 48% quality at present on bbc ect so it can all only get better though i am supposed to be able to get a better signal from hannington i did try this transmitter with no luck and guildford but the hogs back gets in the way as i said all the aerials in my road point to crystal palace so who am i to argue lol.
again many thx for the amazingly fast reply.

I bought a digitop aerial after 2 One 4 All Aerials SLX Gold digiTop Amplified High Performance Indoor: Amazon.co.uk: Electronics and on the day i bought it - perfect - all freeview channels perfect signal. However the next day and today I've not got such good signal/reception on at least 4 or 5 channels? Is it the aerial? Should i re-tune my Freeview built in tv? Or should I just continue to play about with my aerial when needed, and hope the signal strengh will be stronger, come switchover time?

AD: As you have posted your query under Crystal Palaces heading if indeed you are in that area then reception from CP can be very variable for many, even when not terribly far away from the station.
Indoor (same room) aerials are not really recommended for Freeview reception because of the signal being so vulnerable to signal fluctuations due to movement within the room, or even through a wall, but the fact that you receive anything at all suggests that you are not located in too bad an area and which only a post code could verify, but come next April 18th when the transmitters involved increase their power from 20Kw to 200Kw you will most likely find that this will rectify your present problems, albeit that what I said about same room aerials still applies.
Once you have a full compliment of channels do not be tempted to immediately re-scan if they drop out at any point, as all you do is scrub them from the memory which requires frequent scans to recover them, as they weren't lost in the first place but just under the reception threshold for your TV or box and will return when the signal strength rises.

I don't know whether I'm tuned to Crystal Palace or Reigate transmitters. The Digital Switchover site says that with my postcode it's likely to be Reigate but that I could get a better signal from Crystal Palace.
How can you tell which you are turned to without getting someone in to go on the roof and check the aerial position? I have a digital aerial, by the way.

Sue: The difference between Crystal Palace and Reigate signals (apart from, perhaps, the direction that they come from) is that the former are horizontally polarised and the latter are vertically polarised.
If your aerial is horizontal, then you are on Crystal Palace and if it is vertical then it is Reigate.
See here for a photograph of aerials in each polarisation:
Aerials, TV Aerial and Digital Aerial
There is no such thing as a "digital aerial", but in some cases a different aerial may be necessary, but that is due to different signal strengths or different frequencies being used than are/were used for analogue.

Sue: Which transmitter will provide the best signal depends on the location. A post code is an extremely large area and results can vary greatly. Furthermore, the predictor does not take into account obstructions such as buildings and trees that will affect reception. It should be used as a guide only.
If you are having issues with reception; for example some channels break-up or disappear at times, then it must be borne in mind that in three months time the transmission power of Crystal Palace and Reigate will be increased (at switchover) and as such is likely to irradicate any issues with the signal going into your receiver being too low (or touch and go).
This means that any changes you make will probably only be needed for the next three months.

Hi jb38 or anyone else really.
Well its actually funny that NOW i've got good reception on all channels...aaah i'm sure it'll all go wrong when I go to bed and my curtains interfere with the position of my aerial and then i'll be starting all over again...no such luck with me I guess.
Oh by the way i should have pointed out i live in the Banstead region (SM7 postcode) I'm told Crystal Palace is my nearest transmitter, but surely Croydon and Reigate are more closer :s hmm
ok so you're telling me not to retune my tv at all? What about during switchover? I thought we all had to do so on the switchover dates?
Also I have an HDTV - why am i not getting the HD channels :s i have all the other freeview channels though - I think.
