If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=2qEQN_FV0Pk Here's an excellent example of a 40 meter vertical antenna that should get plenty of contacts, despite the propagation issues facing most radio amateurs.  K8YIO has done a commendable job of designing and building this simple antenna made from locally available materials. Please note the radial ground system which is necessary for maximum efficiency of a vertical antenna.  This antenna could also be used on the 15 meter band, as a third harmonic of 40 meters.  Multiband operation is possible by using balanced feedline into a suitable tuner.
