it is a strange one ? I messed with it a little last night , seems like it has to be mounted to metal ,by itself , leaning up against a tree ,no match ,so IM guessing it needs a ground plane of some kind ? I did lay it sideways accross the top of my car (antenna to metal) and I was getting a 1.2 match but it was very touchy ,moving the mic around or even touching the radio I was using would flucuate the SWR in a big way , just laying accross the top of my car about 5 ft of the ground ,I did get a few good radio checks from some truckers ,IM wondering if the push pole that one might mount it too would make for the ground plane needed for a talkable SWR ? .....very strange to say the least or it's just a major piece of junk that somebody thought they could make a dollar on ? Hmmmmm
