FEATURES

The 20M5 is getting rave reviews! It is staying IN the air and ON the air while others are coming apart. The best part is that it is the way it make contacts enjoyable. The 20M5 has a clean pattern and great gain over the band as a result of careful computer optimization and construction. If you like you can customize it to your favorite part of the band and performance preferences. Stacked with a mate at 62 feet apart a full 3 dB improvment can be realized. Most other designs won"t give you that advantage. Physically, the 20M5 has been carefully engineered to maximize strength and durability while keeping weight and wind area under control. A pair of machined, 1/2" thick aluminum boom-to-element plates and saddles ground each element and make spacing adjustments easy along the 3" x .125" wall boom. Elements taper in 1/4" steps from 1-1/4" to the adjustable 1/2" tips. A sturdy Hairpin match grounds the driven element and makes matching easy. All critical hardware is stainless steel. The 20M5 is sold factory direct to discriminating Hams.
