Thank you for adding the radiation patterns.
Can you explain what it all means.
EG.
Is 0' north?
Are the numbers going out from the transmitter the strength of radiation.
Are the circles in feet, millimeters, miles, kilometers?
Is the red line the danger line.

Also as the Haywards Heath relay is on the top of some flats, would this affect them if they live in the top flat?

Mark A.: Oh right, an explanation might be in order.

The top is north.

The circles are the level of attenuation, with the outside being 0dB (ie, full ERP) and the inner lines are the attenuation in decibels, up to -18dB with the inner point meaning "no signal".

The actual attenuation patterns are actually 3D, but they are very hard to show in a 2D diagram.

At some point I will adjust the routine that draws the coverage maps to take into account the attenuation.

Interesting, and thanks, but why are the redacted ones redacted? Seems to include many/most major tx?

Steve: A very good question. It would appear from my discussions with Ofcom and BBC people that there were (perhaps still are) international negotiations still ongoing.

"International" in the sense of RoI, France, Belgium and Holland where there is some signal overlap.

Hi ... how can i find out what a particular mast is called ?
/Users/G4Home/Desktop/Picture 1.png if you can access this screen grab, this is it ! Close to Nanteris Wood, Bronygarth, NR WREXHAM in Wales.
All the best, Stephanie

I think Nanteris Wood is in England - Oswestry SY10 postcode if that helps.

I live in Chirk but can't envisage a mast.

Sorry Steve my mistake ... it is on the English side of the border ! Thanks for your help, appreciate it. I am house-hunting from a distance & the names of some masts marked on the map are totally mysterious - any tips on how to find them out please ?
All the best, Stephanie
