The symbol shows the location of the Black Hill (North Lanarkshire, Scotland) transmitter which serves 940,000 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 Black Hill (North Lanarkshire, Scotland) mast?

andrina mallon: TalkTalk don't have anything to do with providing the signal received by your communal aerial. Have you checked whether any neighbours are having the same problem? You need to report the problem to whoever is responsible for maintaining the communal aerial system.

Transmitter engineering: G132XL Aerial on roof.
After re-scanning (i've tried resetting, auto, manual scan etc multiple times) it goes between 0-20 channels with full or flickering signal.
BBC channels have never returned.
Currently have zero channels
Problems started last Thursday or Friday.
Thanks

Billy: While engineering works is a possible cause, another could be the presence of a new mobile phone base station operating in the 700MHz band, a band which was previously used for TV. Restore TV [ https://restoretv.uk/ ] is the organisation responsible for addressing problems of interference to TV reception caused by these base stations. It says your postcode has received a postcard telling you that you are in an area that could potentially be affected. This isn't to say it will definitely be the reason for the issue because it isn't an exact science. Contact Restore TV and they should send you a free filter.

Billy:
As noted in the post before yours, the Black Hill transmitter is listed for Planned Engineering and has been so for several weeks now. Arqiva never provide details of the work, what it involves or how long it may last, some of which can be weather dependant.
IF you are suffering interference from a new/upgraded mobile mast, then it's more than likely that your reception could be affected by the more recent engineering.
As noted by Steve, your postcode should have received a postcard, checked here -
https://restoretv.uk/post…ure/ so contact them for a Free Filter.
It sounds like the mistake you've made is to rescan/retune when you had no signal, you cannot tune to a signal which is not there, the usual effect is it just clears the correct tuning that you previously had.
Also, your postcode is predicted to receive more than one transmitter, so to check that it is Black Hill that you should be receiving, check that your aerial is pointing at compass bearing 99 degrees - that's just 9 degrees south of due E, and the aerial rods (or squashed Xs) should be horizontal.
If that's correct then your best option will be to MANUAL tune each of Black Hill's UHF channels.
As listed at the top of this page, Black Hill's UHF channels are C46, C43, C40, C41, C44, & C47
(where C means UHF channel).and that's in the multiplex order
BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, & ArqB/COM6.
For which TV channels are carried on which multiplex see
Channel listings for Industry Professionals | Freeview
If the signals are still weak, you may have to try manually retuning a given channel several times over a period, until you get them all back. Once you have a particular multiplex retuned do NOT retune it again (or do an automatic retune).
Apart from the possibility of interference causing your set to "see" weaker signals, your aerial installation may have issues, check that it's still pointing correctly, that the downlead isn't flapping in the wind, check all your accessible coax connections for corrosion or water. If you have flyleads between aerial connections and equipment, check these haven't gone faulty.

Is there still work on as the work in progress is active?

Rai:
The transmitter is no longer on the Planned Engineering list, however we know that the lists aren't always 100% accurate.
Are you having problems with reception?
If so, please provide a full postcode and describe the problems you are having and which channels are affected, along with any checks and actions you've done.

Rai: The Freeview predictor gives glowing '100' scores across the board for all six main multiplexes and the local multiplex from Black Hill at your postcode, suggesting excellent (the best) reception. I think this may be over-egging the pudding somewhat.
The ground level at properties in your postcode is around 15m give or take a few metres. 200m or so to the east, in the direction of the transmitter, the ground is 20m or more higher on which there is the school, church and several apartment blocks.
The higher ground can be seen on this heat terrain map:

Steve Donaldson: I do need to point between two trees then beyond that is a tree, then a block of flats in the line of site of the transmitter. the antenna is probably around 2-3 meter above the top of the roof. Just cant understand why it was good before but after works the quality went down. tried all cables etc in the house or I have bad luck with my location and line of sight ? but then why was my signal quality above 70+.
