Default radar question

i am installing a spotlight on my roof about 3 1/2 feet in front of my radar, the lowest part of the antenna paddle is 16" off the roof and the spotlight is about 10" high does anyone think this may interfere with the radar signal? thanks...

Radar beams shoot out from the antenna (paddle as you called it) at distinct angles that define both its width and its height. The width of the beam is a function of the width of the antenna so they vary all over the place as antenna lengths do, but the vertical width of the beam is fairly consistant across brands and models. They generally have a beam that is of about 25 degrees vertically, with half of its shooting above and half below an immaginary plane that is parallel to the antenna. So the beam looks like this < With your spotlight 6" below the antenna and 3.5 feet in front of it you are probably just under the beam, though not by much. Of course its not really important anyway. Being down on the very edge of the beam the spotlight isn't going to present any problem for the Radar and the Radar is not going to do any damage to the spotlight either.
