Hy-Gain V-4R 70cm antenna is acollinear, 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 ruggedized V-4R is suitable for personal use, repeater, and packet BBS service.
The feedpoint is a high quality "N" type connector that is protected from the weather within the lower radiator. 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.
