Fan Dipole Antenna
Here's another great HF antenna idea from Mike (M0MSN0. In this video, we get a clear, simple explanation of how to design, build, and test a "Fan Dipole Antenna."

Aimed at anyone with an interest of DIY antenna building. this is a rather oversimplified explanation of how the "Fan Dipole" works. As a cut length of wire is resident at a given frequency with a impedance of 50 Ohms, If you feed RF energy to the wire at the same frequency, the wire will radiate the RF with little to no returned energy. If however you move away from that frequency the impedance of the wire changes and the cut wire becomes resistive, the RF energy being pass it will start being return to to its source, (high SWR) A Fan Dipole has multiple cut lengths of wire, resident and key freq
