I mounted mine on the back corner of the body, using one of the old corner molding holes. Doesnt get knocked around that way.
Make sure it has a good ground to the "body" of the vehicle. You want an "RF" ground to the body, not a "DC" ground to the battery for antenna return currents. They are two different types of grounds.
so if i am mounting one to my rear bumper, how much above the roofline should it be? im wondering how long of a firestik to get...
Hey, what about mounting the antennas right into the mirror casings? For mirrors like this:
Instead of using one of those clamp-on brackets with the bolts sticking out and coax hanging out - put the insulated stud right through the little stainless housing on the side of the door. Then the cable can be routed inside the mirror mount and you would never see it. Anybody ever analyze the amount of space in there?
