Simple Ham Radio Antennas--How to turn a vertical into a beam. Post #665.


If you're having difficulty viewing this video, please insert this address into your browser search box: https://youtu.be/FUV4dqhQvYA.  Here's a simple way to get a little more gain out of a 20 meter vertical antenna.  Rob turns his 20 meter vertical antenna into a beam using a reflector wire from the top.  For 20 meters, he used a wire a little more than a half wavelength on 20 meters.  The vertical portion of the antenna is 5 meters/16.4 feet, with the top wire measuring 5.1 meters/16.7 feet running horizontally.  Rob says not to ground the reflector wire. Keep the reflector wire approximately 30 cm/11.81 inches above ground.  You should see some improvement in the performance of your 20 meter vertical antenna after you make the changes suggested by Rob.  For the latest Amateur Radio news and events, please check out the blog sidebars.
