The symbol shows the location of the Sandy Heath (Central Bedfordshire, England) transmitter which serves 920,000 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 Sandy Heath (Central Bedfordshire, England) mast?

Very informative post Mike, thanks - I was curious about the Vertical beam tilt

Would the mux magician from Amazon uk be enough to fix my problems from a few pages back? Is suitable for this transmitter? Would there be too much signal being boosted?

if the transmitter is down and i cannot get any tv. does that mean i can have a refund on my tv licence as i am not getting what i have paid for?
also digital isnt as good as analogue as if there is a storm there is a problem with signal!
this is not being rude or disrespectful just asking a fairly sensible question.

mr weet: No refund is due to your TV Licence unless you sell your TV set.

Digital TV more resilient to weather-based faults than analogue.

The current issue are planned engineering work, not faults.

joe: First, check that your box or TV can properly handle 8K mode. If it can't, it may have picked off-beam transmissions from Crystal Palace rather than the desired ones from Sandy Heath, when you retuned at switchover. The signals from Crystal Palace could still be strong enough to pick up, but a lot closer to the 'cliff edge', meaning they come and go. There is a list of some equipment known not to work at…ment .

At present, Mux C at Sandy Heath is still using its pre-switchover 2K mode. Crystal Palace - which switches next April - is still broadcasting everything in 2K mode.

Some boxes will store the first channels they find when scanning, starting at C21 and working their way up, so it could still store Crystal Palace in preference to Sandy Heath. In this case, usually the other set(s) found is/are stored somewhere else in the programme guide - often at channel 800 and up.

Check the frequencies that the box shows for each channel group at the top of the page - this is often in the tuning menu or in System Status. If it says 25 for BBC One, 22 for ITV1, 28 for BBC Four/CBeebies then it's using Crystal Palace. You should do a full reset with the aerial unplugged, to clear all stored channels, then manually tune on C24 and C27 for BBC and ITV. If the box won't detect anything on those channels, try without the amplifier. If it still won't, it may not be able to handle 8K mode at all.

I would strongly recommend you don't try to change your roof-top aerial yourself. If you do require a high-gain aerial - and the prediction suggests that you won't, once all changes are finally complete (9 May next year, unfortunately) - a grouped aerial will be smaller for the same amount of gain. Those tri-booms are, frankly, overkill for most people.

If it's definitely tuning into Sandy Heath, the problem could easily be that water has got into the cables or outdoor connections - this affects the highest frequencies first and worst. ArqB is way up at C67 at present, and Mux A/SDN is shown as the lowest probability of reliable reception at your postcode, for now.

As you can see, it's not a simple answer, and professional assistance might get the problem sorted out sooner.

fair enough, but if you don't ask as they say.
so can i ask how i can watch the tv i require whilst engeneering in progress?
on the railways they have buses in when they have engineering so no backup transmitter?
prehaps they real reason for riot was that there was no tv in tottenham haha...
just joking of course, unfortunately i can't watch the news so i don't know.

So there will be a need to retune for Sandy Heath...

And the final National retune day is?
Oh, and I saw somewhere, but can't find it, at what date do the rest of the Mux's go high power? I get enough RF down the co-ax to split/2 and then split/4, except I'm still having to use an amp for the lower power mux's, as they are borderline.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
