Hy-Gain V-4R Collinear Gain Vertical Antenna
The new Hy-Gain V-4R 70cm antenna is a collinear, dual 5/8-wave, omnidirectional, vertical antenna for the 420-450 MHz amateur band. The V-4R 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 a nominal 50 ohms.
The V-4R also features a mast-to-mast bracket that will accept up to a two inch O.D. mast. The V -4R can be used outside of the 70cm amateur band. Graphs are supplied so that the antenna can be set to any frequency between 400 and 470 MHz.
