New to scanning but need help please. I have a Uniden HP 2 also a Whistler TRX-1 that I want to mount 2 separate antennas on the gable end of my garage and house to pickup signal better. Can someone suggest a good antenna. I want to be able to take either unit from house to garage to plug in. Also will I need to ground the antennas. I live in the Flint, MI area.
