Comment: If you have no room for a tower, but still want the performance edge extra height gives your VHF/UHF signal, you may want to try this intriguing idea from Glenn (N6FN). Glenn has built a rig that "transmits significant power using a thin wire.  The wire is used to send the power at high frequency down the wire at which point it becomes more like a transmission line than a conductor."  Glenn adds that his signal " is rectified to DC on the other end to power a quadcopter drone" supporting the antenna wire. Glenn has included some interesting graphics and a video showing the evolution of the drone supported antenna. For the latest Amateur Radio news
