Full of questions this week. We were given a pair of antennas. One of them is at http://polariswebdesign.com/Trucks/cbantenna.jpg . How do these mount? I don't get it... I have a magnet mount but can't seem to find a good place to put it. I had it on the fender and don't like slamming the door on the wire. Plus it's so big, trees like to take it off on the trail. Thanks for any advice.
