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.
