Fan Dipole: How it works, a simplified explanation.

All you need to know about the fan dipole, an easy-to-make multiband HF antenna.  This antenna is perfect for the ARRL Field Day event or for use at home.

Mike (M0MSN) does a good job of explaining the theory, construction, testing, and use of this versatile antenna.

Here are a few comments from Mike (M0MSN):

Fan Dipole : How it works. 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 frequencies and as the frequency changes so each length of wire becomes resident and the others represent high impedance and so become gated to the RF forcing the energy down the route of less resistance.
