INSTRUCTION MANUAL
GENERAL
The new Hy-Gain V-2R, two meter antenna is a
collinear
5/8-wave
antenna for the 144-148 MHz Amateur band. The
V-2R features two sets of 1/4-wave radials which
properly decouple the lower 5/8-wave radiator
from the mast. It also features a 500 watt
enclosed coil that matches the antenna to
nominal 50 ohms. The ruggedized V-2R is
suitable for personal use, repeater, and packet
BBS service.
