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 Sandy Heath (Central Bedfordshire, England) mast?

Hello,
I have a digital arial that has to be re-positioned to Sandy Heath. It is on the roof and my postcode is NN15 5BZ. What will be the compass heading in order for me to position the arial please from this location.
Regards,
Mike Hoare

Mike Hoare: The Digital UK checker shows that Sandy Heath is on a bearing of 131 degrees from your postcode. You don't have a digital aerial as no such thing exists. Your aerial will need to be a wideband type for good reception of all multiplexes from Sandy Heath.

Hi, we have regular problems with DTV channels BBC1 BBC2 etc (channel 27). but the HD channels are fine. We are tuned to Sandy Heath. The signal strength is good but the quality is poor/medium. This usually happens when there is a period of high pressure. Is there anything we can do? Our post code is le16 7bt
Aerial is on the roof.

M. Walsh: If this is only happening during periods of high pressure then it's unlikely that anything can be done. The high pressure allows radio signals to travel much further than normal, causing interference from distant transmitters which broadcast on the same frequency but which are not receivable under normal conditions.

NINA: There is no engineering work showing for Sandy Heath. Have you checked for any loose or damaged cables or connections behind your TV? Please provide a full postcode so that we can see where you are in relation to the transmitter and your predicted coverage etc.

Mr Walsh . the coverage checker shows a strong signal at your location. You are inland so should not get much continental interference . I wonder if your aerial system is too sensitive .(overloading the tv) . You should not need an amplifier . I would remove it if you have one and you may need a small attenuator to reduce the signal further . Without an amplifier you should aim for a signal strength reading of no more than about 80%.

This evening (13-2-2019) we have had major disruption of the main TV Channels, making them unwatchable for almost all the time. This occurs a number of times each year, although some channels never seem to be affected (Channel 37 "Quest" for example.
We have a brand new roof arial, with internal signal booster, and yet both before and after the replacement arial, this keep occurring. The arial installer about the alternative, Talconston, which is equidistant from Sandy Heath, advised us NOT to change , as it was no more reliable.
We are aware that in high pressure weather systems, signal strength at the extremes of range are reduced - but to lose signal altogether on ONLY SOME (The Main) channels is unacceptable and inexplicable

You have explained it yourself. High pressure causes numerous recepotion problenms and often affected just some channels and not others. As it is a perfectly natural phenomenon there is noth anybody can do about it. It has been known about the many decades.

Have no signal from Sandy heath.....can get Sky news,and various other channels
but no BBC ,Itv or Channel4 or 5.
We are on freeview.
Have tried turning off booster...no difference.
All connections have been checked and ok.
We have experienced this problem before and then it clears.
Is this an atmospheric issue ?
There is a mobile phone mast near us in the village... could that cause interference?
Postcode is PE3 9NH.
THANKS
