Invented by G5RV amateur, R. Louis VARNEY published for the first time the technical documentation of its antenna in November 1966.
The G5RV wire antenna have 2 versions: 1/2 half size, about 16 meters long, covering 4 HF Amateur bands from 7 to 30 Mhz 40/20/15/10m, or full size of about 31 meters long and covering 5 HF bands from 3.5 to 30Mhz: 80/40/20/15/10m.
- Multiband with excellent result on amateur bands 80/40/20m, good on 30m and 17m, and average for 15/12/10m
- Efficient for local traffic and DX when placed high above the ground above 10 meters (7m minimum)
- Small footprint and lightweight portable
To use G5RV in multi-band, without any risk for transceiver, the G5RV antenna must be associated to a tuner.
Delivered to assembly: 2 long wires, 2 insulators mounted at the end of the 2 wires, 1 ribbon cable connector SO-239 (UHF-Female), assembly instructions.
Receiving frequencies: 7-30 Mhz (1/2 size), and 3.5 to 30Mhz (full size)
Transmitting frequencies: 7, 14, 21 and 28MHz (1/2 size) and 3.5, 7, 14, 21 and 28MHz (full size)
Total antenna length: Around 16m on the half-size version (2x longs wires of 7.8 m) and 31m on the full-size version (2x long wires of 15.5 m)
Length of coaxial cable ribbon: 4,66m (1/2 size) and 9,35m (full size)
Power: 300 Watts nominal 500 Watts PEP
Impedance: 50 Ohms
Connector: SO-239 (UHF-Female)
This antenna need to be use with a coaxial cable of 50 ohms with a length of between 14 and 28 meters recommanded. For use in multi-band, without risk for the transceiver, the G5RV antenna requiere a tuner.
The ribbon coax cable must be held vertically for best results G5RV the antenna should be mounted as high as possible, with its center at least at 7 meters from ground (10 meters ideally), and can be mounted in horizontal or inverted V position (with an angle between 90° and 120° max).
