I've been studying for my technician license and have been researching options for maximizing 10 meter comms in my semi truck. I've throughly read through ground plane and mounting information and I have a few questions.
How does ground plane analysis jive with the common placement of cophased 11 meter antennas in use on semi trucks? If this configuration is an exception, or if the ground plane is achieved via placement, can the same be accomplished with the same placement on 10 meter?
Additionally, I'm contemplating a servo rotating design using a high mounted 102" whip that i can install either on the back corner or side of the sleeper cab for use while parked. My original thought was using a ground strap to achieve ground plane however, your analysis indicates that this is insufficient. If I utilized a cophased 102" on each side of the cab, would the servo rotated design perform as well as the fixed mounted cophase designs do on 11 meter? If a ground plane is still inefficient, would the introduction of ground plane adapters resolve the issue, being that the base of the antennas would be about 13 feet above the road surface?
