20 Meters. This amazing tri-bander, using a dual driven
7-element system maintains a VSWR of less than 2:1 across
all bands, including ALL of 10 Meters. No compromise on gain
performance was needed to achieve this efficiency. A unique
combination of trapped and monoband parasitic elements
produces a front-to-back ratio of 27 dB. The antenna includes
exclusive diecast aluminum, rugged boom-to-mast clamp, and
heavy gauge element-to-boom brackets. Comes complete with
BN-86 balun. (This is a $700+ beam new, it is used with a
