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
  • Does not require a balun to operate, the two-wire line (frog ladder) is used to adapt directly to 50 ohms.

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.

G5RV FULL SIZE
Excellente antenne en Full Size, correspondant à mes attentes. Juste un petit problème de sertissage de cosse (côté isolateur "os de chien"), le lendemain de l'installation l'antenne était au sol... Réinstallation avec cette fois-ci un bon sertissage maison et le tour est joué !

Très déçu de cette antenne, la fabrication est très mauvaise, la ligne bi-filaire tient à peine sur les cosses et le ROS est très mauvais. Impossible d’utiliser cette antenne. Ce n’est pas de la qualité.

Envoi extrêmement rapide.
J ai du refaire le sertissage des 2 cosses de l antenne car sertissage tres mal dénudé et il n\'y avait qu un brin de serti.
Acheté également 2 serre câble pour fixer l antenne.
Si non marche correctement comme annoncé.
Juste une petite modification en fait mais rien de grave.

G5RV super!!
suite a une nouvelle installation rapide , achat pratique et fonctionnelle s\'accorde correctement avec seulement la boite de couplage integré du 17m 160 m sans soucis sur les bandes au dessus, ca fonctionne aussi mais c\'est preferable de passer par une verticale.
