Yes, you can disable the radar in a certain azimuth, it is routinely done if a radar is close to a residential area. Unfortunately if you look at the situation in Aberdeenshire for example, youŽd see that the radar tower would be useful as a nice flower pot stand or water tank but little else.
NATS/MOD receive more than 3000 consultations each year, ok, they are quite geographically sensitive with the north significantly "worse" than the south but these things are flourishing.
Here's a snapshot.... but may not include single farm type turbines, we're quite lucky down south, but you'd be scared at how many of these things are around in other areas.
