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?

My neighbour and I both live in SG9 0BA postcode and had some signal loss yesterday and total loss this morning at around 1 pm. At 13:15 pm we were both OK. Has there been any work on the Sandy Heath transmitter that would have caused this?

As back up to my claim of very intermittent freeview reception please be aware that I have 3 independent tv sets fed from 2 separate aerials. Could someone from Sandyheath freeview please look at this web site:-
Freeview TV signal down for people across the whole of Cambridgeshire - Cambridgeshire Live

all day 30/12 and into the morning of 31/12 I am having signal problems in the PE15 are. Sandy Heath is our nearest transmitter. Many stations that I can normally watch including BBC channels are not coming through and reporting "no signal"

Chris.SE: can we assume that scheduled moves of sandy heath channel allocations will be postponed if they conincide with unusual tropospheric radio propagation. Or are we to see messages to return at a time when the new frequency allocation will be blocked by interference.
One must wonder why the mobile phone companies are so keen to gain access to the higher Freeview TV frequencies, when they are subject to tropospheric RF ducting and scattering. Something that is going to become even more common due to the effects of global warming. Are the mobile phone operators not concerned about the disruption to their services when they attempt to use these frequencies in the mobile network backbone.
While the 5G is not directly responsible for the current free view interference, the sell off of the high frequencies in the band, must have had an impact on channel reuse distance planning, squeezing the free view channels closer together and thus reducing the available frequency reuse allocation distance, making co-channel interference more likely.
