I want to eventually install a dual bander in my UTV, a Kawasaki Teryx. It has a plastic roof (the aluminum roofs are about $800) so I am contemplating how to best install the antenna. I could use a no ground plane antenna but they tend to be long and would have to be mounted on the side of the roll cage to clear overhead obstacles like tree branches. The shorter dual band antennas require a ground plane. Does anyone have any ideas on how to establish a good ground plane?
