Now that HF propagation is favoring the 160/80/40 meter amateur radio bands, you may want to consider a multiband antenna covering these bands.  K7PP wanted to cover 160/80/40 meters with a single feed line without using an antenna "tuner", and still be effective, inexpensive, and relatively easy to build.  In this video, K7PP takes us from start to finish with the "classic" Fan Dipole Antenna.  The antenna has withstood several years of bad weather and continues to provide reliable 3-band coverage.  K7PP says the only weak spot in his antenna design is the bamboo spreaders which have taken quite a beating from winter snow and ice. You can also configure this antenna as an inverted Vee, thus simplifying the construction process and eliminating several support masts.  The fan dipole is a reliable, simple, and effective HF an

You can still design, build, and use a multi band HF dipole antenna even if you don't have an antenna "tuner", "traps", or a lot of space.  In this video, K7PP shows us step-by-step how he created an efficient "Fan Dipole" antenna for his medium-sized back yard.  Just follow the easy directions in this video and you soon will have an efficient, relatively inexpensive, and effective multi band HF dipole antenna for your station.

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
