How to Build a ZS6BKW Antenna (optimized G5RV) (https://www.vk4mdx.wordpress.com/2013/09/02/how=to-build-a-zs6bkw-antenna-optimized-g5rv-antenna/). Accessed on 05 May 2016, 02:21 hrs, UTC. Author:  David Olsen (VK4MDX). The original G5RV antenna designed by Louis Varney (G5RV) (SK) continues to serve radio amateurs well around the world.  Although Varney clearly designed this dipole as a 3/2 wavelength antenna for 20 meters, it can be used on amateur radio bands from 80 meters through 10 meters with a suitable tuner. Performance on bands other than 20 meters can be variable because of many factors, including feedline length, the type of feedline, and very high SWRs on some bands.  As a 20 meter antenna, the G5RV does an excellent job.  On other amateur radio bands, performance often suffers. However, with a few modifications regarding antenna element length and the correct combination of 50 ohm coaxial cable and 450 ohm ladder line, it's possible to improve t...
