Of course, this is 'in the beam' though....

Thanks Steve. I calculated the (straight line, fixed height) distance on google maps, and I got 390 metres. The distance to the top (220m height) is roughly 450m, which is closer to your minimum safe distance of 434 metres (phew!), but still...

Do you know where I could find the radiation pattern for the CP transmitter?

Steve, I found the radiation pattern at ofcom:

Is the azimuthal angle measured with respect to North?

Hi Helder.

Since this is now going rather off-topic for the thread, I shall reply by Private Message.
