Hy-gain VB-25FM

This antenna is a 5-element, 2-meter beam optimum spaced on a 75" boom. It features high forward gain and an excellent front-to-back ratio. The antenna is end mounted giving it the advantage of no mast decoupling and a broad frequency response. This antenna now uses stainless steel hardware in most locations except for the U-bolts. Also, this antenna now features a NEW boom-to-mast bracket that fits up to a mast diameter of 2 1/16 inches.
