If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/MKmpZ7j2ms8.  In my last post (#722), I listed a website that would give you the basics of designing and building a Moxon Antenna.  In this post, we shift from theory to actual construction, as   Stefan (DL7AOS) shows us how to build a simple 20 meter Moxon Beam Antenna.  You'll probably need some help in erecting this beam, but the performance is worth the effort.  I've seen a few 10 meter Moxon Beam Antennas at various Field Day Events, and their performance is quite good.  A Moxon 20 meter Beam Antenna would make an excellent radio club project.  For more information on this type of antenna, visit http://www.ac6la.com/moxgen/DL7AOS/DL7AOS.htm.  Good luck!  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.

Simple Ham Radio Antennas--The Moxon Antenna Project. Post #722

The Moxon Antenna Project. (http://www.moxonantennaproject.com). Accessed on 20 March 2016, 01:15 hrs, UTC). Author:  Steve Hammer (K6SGH). Comment: Here's all you want to know about the stealthy gain antennas designed by the late Les Moxon (G6XN).  Webmaster Steve Hammer (K6SGH) has done an excellent job of explaining the theory, design, and working properties of this unusual rectangle antenna that can be crafted for both HF and VHF/UHF work. Steve recommends you start with a simple rectangular moxon for 6 meters and 2 meters.  Steve says, "The moxon rectangle is a superb antenna that is fun to build, works like a champ and is virtually indestructible." The moxon design is great for portable, emergency, Field Day, and home use. Try one--you'll be pleasantly surprised. At the end of his article, Steve lists more than 30 moxon projects you can try at your home or next Field Day.  Have fun! For the latest Amateur Radio news and events, please check out the

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/LbEAwAG1KMA.  A trap dipole is a good choice if you want to operate on only two or three bands and don't want to adjust an antenna transmatch (i.e. tuner/coupler) to change bands.  If you follow the instructions given by Peter Parker (VK3YE) in this well-produced video tutorial, you'll have this simple, efficient antenna working for you in short order.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

Simple Ham Radio Antennas--Ham Stick Vertical Dipole Antenna. Post #719.

If you're having trouble viewing this video, please insert this title link into your browser search box" https://youtu.be/CbQwLPVmG70.  In this video, Brian Downs show us how to use Ham Stick style Antennas in a vertical configuration. This arrangement could come in handy for portable operations or for areas with restricted antenna space.  Brian uses a set of 20 meter Ham Sticks to make the vertical dipole.  You can get 20 meter to 10 meter coverage if you feed the antenna with 450 ohm ladder line, use a 4:1 balun, and a short length of 50 ohm coaxial cable to connect the balanced line and balun combination to your antenna transmatch (i.e. "tuner").  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  You can follow our blog community with a free email subscription or by tapping into the blog RSS feed.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).
