Simple Ham Radio Antennas--K7PP's Multi Band Fan Dipole Project Ham Radio. Post #681.
If you're having trouble viewing this video, please insert this address into your browser search box: https://youtu.be/SXqSY5JKQzs. In this video, Peter (K7PP) shows us how to make a simple multi band dipole using a single coaxial feed line attached to a common center shared by several mono band dipoles. Each dipole is tuned and trimmed to the band of preference and connected to the 50-ohm coaxial cable feed line. Each dipole is "fanned out" below the longest dipole element and secured with stakes. In this example, Peter is using the lower HF bands below 40 meters, so weight may be a problem. I've built several of these fan dipoles and have found that an inverted V configuration is a bit more stable and easy to adjust if necessary. With each monoband dipole properly trimmed, an antenna transmatch (i.e. "tune") isn't necessary to work several HF amateur radio bands. At my home, a telescoping fiberglass pole approximately 33-feet/10.06 meters long supports a "fan" inverted V dipole which covers 40, 20, 15, and 10 meters. A very simple, effective antenna that will get you on the air quickly at a modest cost. For the latest Amateur Radio news and events, please check out the blog sidebars.
