Simple Ham Radio Antennas

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/mgEibY3INHo.  Here's an interesting antenna that is suitable for small city lots and for portable operations.  Dave (K4WDG) does an excellent job of explaining the theory, design, and use of this dipole variant.  Dave has two ham shacks and owns two commercial radio stations, so he is familiar with most of the antenna theory that supports this antenna.  This antenna is simple, inexpensive, and offers some directivity in the direction of the slope.  You can change the direction of your signal by tying off the sloped dipole to various stakes placed in your yard.  The upper end of Dave's sloped dipole is approximately 35 to 40 feet/10.67 to 12.19 meters above ground. I've built a few sloped dipole antennas and they work very well.  If you feed a 40 meter sloped dipole with 300 ohm television twin lead or 450 ohm ladder line and attach this feed line

A good, basic introduction on how to use the Spectrum Analyzer from Arash Kamanigir. In this easily understood video, Mr. Kamanigir uses an Analog Arts Spectrum Analyzer (http://analogarts.com) to show how to capture a signal, measure a signal's peak and strength, analyze frequency bands, adjust resolution bandwidth, and make other signal measurements at your amateur radio station.  A nice reference video.

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

In this video, Stan Gibilisco (W1GV) explains the theory, design, and construction of this intriguing antenna. Although this antenna is a bit more complicated than a vertical, it won't take too long to duplicate Stan's design and have it operating by the end of the day. Take your time and be sure to lay out a good ground radial system.  Good luck! For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.
