The G5RV antenna has been discussed for decades, so there’s little point repeating the theory behind it. Instead, this project focuses on something less common — adapting the classic G5RV concept for operation on the 2 meter amateur radio band around 145 MHz.
The idea started as a simple experiment. I wanted an antenna that could be packed easily, carried onto a hill, and assembled in minutes for portable VHF testing. The dimensions of this version make that surprisingly practical.
Unlike many multiband antennas, the G5RV antenna 2 meters is not designed as a conventional half-wave dipole on its highest operating frequency. In this configuration, the antenna behaves as a 3λ/2 center-fed system. That detail changes the matching requirements and makes the feed section especially important.
