FEATURES:
The 20M6-125 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, exceptional front to
back and excellent VSWR never exceeding 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 finer, stronger antenna available today.
