KK5BL How To Build A G5RV Antenna - How to build a G5RV Transmitting antenna Originally posted to the packet bbs system by KC6CFF. The G5RV is an easy-to-build 80-10 dipole requiring no traps. All bands are covered, including 30, 17, and 12. The G5RV has high SWR, by design, on most bands and a tuner is required
