|
The 20M5 125MPH Version is the perfect balance between wind area and performance. It featuers improved gain and F/B across the 20 meter band. The 20M5-125 MPH Version is computer optimized mechanically for maximum strength for it's wind area. Mother nature will hate this one ! Three different optimization options allow the antenna to be customized for your bandwidth and performance preferences, from full bandwidth (FB) to gain and F/B boosting configurations especially for CW, and low phone (CF). Plots with gain and F/B figures are supplied for all options. Physically, the 20M5 125MPH Version, features tapered elements, each secured with a pair of machined, 1/2" thick aluminum boom to element plates secure each element and permit spacing adjustments on the 2" x .125 wall boom.
