The 14.6-6-125 is a medium spaced, high performance, full band coverage 6 element Yagi, computer optimized to squeeze the last drop of performance from this boom length. The design provides virtually flat gain, but front to back has been sacrifice for gain. VSWR never exceeds 2:1 at the upper band edge. Larger, sleeved elements and boom provide the 125 MPH wind survival factor. Construction includes machined boom to element mounting plates and a rugged hairpin match. This antenna will be in the air for many years, keeping you on the top of the pileup in spite of Mother Nature ! There is no finger, stronger antenna available today.
