I picked up a variety of antennas at a swap meet a while back, and am having trouble characterizing an unlabelled HF (or low VHF?) vertical element that screws into a stud in a magmount I also brought home at the time. My analyzer is giving strangely varying results that I suspect are more due to the coax/mount than the antenna itself.
The magmount and elements are the "stub" kind (3/8" I believe) in that there's only a single electrical connection between the two. I'm assuming the center conductor of the coax should be wired to this.
But what should the shield be wired to? My magmount is in fairly bad shape and depending on the breeze the chewed-up outer conductor either shorts up against the stud, or just hangs loose on the bakelite shell. How would this have been terminated originally?
