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?

Why is a wideband aerial recommended? If the top part of the band is to be used for 5G would you not then be left with an aerial that is designed to pick up unwanted signals? I would have thought an aerial optimised for the lower channels would be better (provided 55 and 56 are still tolerable).

Scott:
The usage of channels 55 and 56 is purely temporary on 30 of the main transmitters until sometime in 2022, when the programmes using the COM7 and COM8 multiplexes will be moved to other locations. 5G will not gain access to the 700 MHz+ band until it has been cleared of all TV broadcasts in 2022. Until then many viewers need a wideband aerial to get those two multiplexes as most non-wideband aerials designed for Group A or Group B are very poor at receiving 'out of band' signals at higher frequencies. If you never want to watch any of the programmes broadcast on COM7 or COM8 then you probably don't need a wideband aerial.
After the changes expected in 2022 the requiremnet will change so you will need an aerial that covers the frequencies between 470 MHz and 695 MHz (channels 21 to 49). The current design of wideband aerials will work perfectly adequately over that range but newer designs may appear will a lower top end cutoff frequency - but they are not suitable for use with the current channel allocation scheme.

steven harper: The only changes to have taken place at Black Hill are that COM7 & COM8 have moved to UHF channels 55 & 56 and the local mux has moved to UHF channel 30. There are no further changes planned according to Digital UK.

Newton Mearns - Blackhill transmitter
All channels on COM8 gone since October
Also strangely at the same tme both my LG tv's show no aerial icon on the main menu
Presumably these tv's drop the icon when the power is not enough
Funny though when the aerial is plugged into the youview dn370 and 372t the signal strength on ch4 is 100% and quality around 82%
LG TV Issue perhaps?
Seen a lot of people mention it in the forums suspecting a damaged I/O board but it isnt its a single issue - happened around same time as i lost COM8.
Switching to my motorised satellite dish for freesat now - freeview is just too unreliable now!

Gary Gemmell:
Please provide a full post code so that we can look up the expected reception conditions at your specific location.
You should also check all the aerial cables and connections as far up to your aerial as is possible to reach safely. Also unplug all coaxial plugs/sockets and then refit. That will remove any corrosion/oxidation from the contacts (that is a common cause of reception problems). Then you should check the signal strength shown for COM8 using the manual tuniong option - BUT DO NOT RETUNE. Ideally you need between 60% and 85% strength (not the quality measure). HD usually requires a higher minimum signal strength than SD.
