For the past couple of months I've working on some interference issues for work. Attached is a picture of the antenna for my "Ultimate Radar Detector". The other end is a Rohde & Schwarz lab grade spectrum analyzer that covers .1 MHz to 40 GHz. No one asks any questions just funny looks. The LEO's that see me sitting just ask whats going on. I had 1 that after I told her what I was doing ask if it was OK for to set up about 100' away to run radar.
