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?

Dear Sir/Madam,

I live in a tenement block; 28 Tabard House, Manciple Street, London, SE1 4DL.

We have a communal aerial in the loft.

However, the TV signal coming from the Crystal Palace transmitter , sometimes breaks up, or goes off altogether.

I have just recently purchased an indoor HD aerial, (max 41db gain) which is working well, however, I am still getting the same problems of picture break up and loss of picture for a few seconds.

HD channel signals are weak and mostly these Hi-def channels break up or freeze, most of all.

I have checked all my connection cables and they are perfectly OK.

Any advice from you would be greatly appreciated, on how I can resolve these problems!

Kind Regards,

Demetrius Skortou

Demetrius Skortou: If the fault isn't with your own wiring or equipment, then it's the aerial system which is at fault and therefore the party responsible should be notified.

At your location, with the transmitter being only 5 miles away with clear line-of-sight, too high a signal level is very much a possibility here. The system's amplifier probably wants turning down a bit.

Some systems are fitted with filters so as to only allow through those channels (frequencies) used by the designated transmitter. If you are not receiving the newer multiplexes then, at the same time as fixing the fault, get the engineer to enable them, these being:

COM7 - C33 - 106 BBC Four HD
COM8 - C35 - 111 QVC+1
L-LON - C29 - 8 London Live

There's also the possibility that 800MHz 4G services could be overloading the amplifier as well. Either way, it's up to the party responsible to get an engineer.

Too high a signal level can appear as too low a signal, or dips in quality. It's like having the volume on a sound system set too high -- the signal distorts and does so to differing degrees depending on the sound.

I live in London Nw7 1ng with crystal palace being my primary transmitter. The signal on multiplex 30 which supplies my HD BBC stations jumps every few minutes with strength constantly being about 30% but quality jumping between 5% and 100% which makes it unwatchable.
All Standard Definition Stations are fine.
I am using manual tune on a Humax HDR FOX T2 and have tried the multiplex 56 for the BBC B HD from the *Finchley* Relay station, which is only one kilometer away, but can get no signal. I have used a attenuator to reduce the signal strength in case that is an issue.
The aerial is on the south facing wall outside, at gutter level facing the Crystal Palace transmitter. I have also renewed the coaxial connections to eliminate that as a problem.
Would be grateful for any advice on the next step please.
Thanks. John Kirby.

john kirby: Looking at the digitaluk page, your doing everything right. 22km is not that far, and Crystal Palace is lower in the scan than the relay station. A Fox T2 has a very sensitive tuner, so you'd expect a great signal - if anything, far too strong, yet your only getting 30% on an HD mux. Yes, its jumping up and down in quality, which is what you'd expect, but its not like your certainly getting too strong a signal. And the Finchley transmitter is very close, and the bearing should be close enough to pick it up, yet nothing.

I think this is JB38's/David Lindsay's area, but I do have a suggestion. You've changed the coax, but have you thought of just getting an indoor aerial, just to check? Just borrow one, and see if its works. The other thing to check is the SD signal level - if its OK but low, then the HD channels are going to suffer more.

Be interested to see what the problem is, because that is just strange!

John kirby: Although fully appreciating your thinking behind trying to receive BBC HD channels from Finchley's 13 watts relay station, you have to look at the situation from the point of view, that even without an attenuator being fitted in line with the aerial input connection on your TV, you might find difficulty in receiving that station anyway, as not only does it transmit on vertical polarity compared to that of Crystal Palace on horizontal polarity, its also situated at an angle roughly half way to the reception dead spot on your aerial, that being 90 degrees from the signal path, the attenuator being the likely cause of killing any signal that may have been received, hence the "no signal" indication.

What value of attenuator have you temporarily placed in line with your aerial facing towards Crystal palace? as the possibility exists the value of said attenuator is too low, this being why you are experiencing the problem.

John kirby: I also meant to mention, that the signal path from the Crystal Palace transmitter suffers from a mild restriction @ approximately just under 4 miles out from you location, something which under certain conditions could have an affect on your reception.

I am moving nearby Penge West station and Crystal Palace. I have been told there are no communal aerials in the building and they are not allowed on the roof. It is likely therefore that I will need some form or portable aerial or other means to get TV. Any thoughts?

Floris: I would suggest that you would have to be terribly unlucky not to receive a good signal so close to the transmitter!

So much so that you should NOT purchase an indoor aerial which has an in-built booster (amplifier). You should also be aware that you could potentially have too high a signal level, owing to being so close to the transmitter, and that this can appear as if the signal were too small, what with the signal level and quality level potentially constantly dipping downwards.

The preferable part of the building as far as reception goes is the side on which the transmitter is. That's not to say you won't receive at the other side. And hopefully with nothing metallic within the wall.

A set-top aerial is a possibility. Or if there's somewhere inside to mount an aerial (facing the transmitter through a wall) then this would be ideal at only 40cm long:

Issue with Ch 23 (BBC A) from crystal palace. Channels are very broken and unwatchable. Al,l other channels seem fine. Tried manual re-tune to Bluebell transmitter (ch 46) but no reception. Think 4G is the culprit!

Any suggestions?
