Our aerial is on the roof at NN38UT, it is pointed across some trees in the distance. Most times we get a good signal but over the Christmas period 2019 it was a disaster. I wanted to watch "Still Open Open All Hours" on BBC1, it was unwatchable. As I type this it is okay but for how long? Using a signal strength meter from Screwfix I only get LED light. I notice from the Brian Butterworth map published 2004 we are in the edge of the reception are. Is this upto date??? There is a masthead Amp. We did have a Optima filter, Chan21-60, 470-790MHz in the loft, I have removed this just for the moment as we were still getting the problems. I have since learnt it should be between the aerial and the Amp-a job for a man with a ladder. In general it the first 16 channels that are affected. Please help if you can.

Just been on website down detector outage maps and nearly half of the country has lost all Freeview TV and radio signals. This is what happens when the government mess about with putting 5G network onto tv frequencies.

IP27 no signal whatsoever. What is up, no notification anywhere that there is an issue! Will someone please advise?

I think it's the weather - high pressure causing interference from other transmitters.

It doesn't make sense that 498 mhz is ok, here in Newton Longville, but 522 is very low signal, causing BBC 1 and 2 to be lost as I retuned!!!!! All other signals are up in the very good, 10/10. So how does weather affect only 522 mhz, but none of the other frequencies

High pressure causes nearby transmitters on the same frequency to travel a lot, lot further.

I would imagine there is a transmitter on 522Mhz that is being lifted further and clashing with the sandy signal.

Some frequencies will be ok as there is no overlap from the temporarily lifted signal.

High pressure causes signals from far away transmitters to be lifted and travel further.

I would imagine there is a nearby transmitter on 522Mhz that is now clashing with the sandy signal.

Other frequencies are ok as there is no clash.

Despite Freeview & BBC saying no problems with Sandy Heath transmitter there clearly IS A PROBLEM. I'm in South Cambridgeshire & have had no TV signal all day. It is clear from all the other comments on here & Down Detector website that MANY people are having problems. Please sort it out asap. Thanks.
