 THE NEW HIGHER POWER DUAL BEAM PRO NOW WITH 6M

Having the ability to direct the main radiation lobe will transform your HF operating experience. Focused high performance design using the most efficient capacity end loading techniques.This is an efficient antenna providing impressive DX performance with minimal visual impact that will help keep the neighbours happy! 

40m*- 30m - 20m - 17m - 15m - 12m -11m - 10m & 6m 

        

The Dual Beam Pro is extremely light weight with a slim attractive profile, measuring just 5m overall. The bi-directional charcteristics require only 180 degrees of rotation to cover the globe. The use of domestic TV aerial chimney stack brackets or gable wall fixings are recommended for the lightweight Dual Beam Pro .... 3.5kg. This antenna can be erected so that it is fixed beaming to your favourite directions, alternatively a light duty antenna rotator can be installed. The Dual beam Pro band coverage: 40m, 30m, 20m, 17m, 15m, 12m, 11m, 10m & 6m. This antenna presents a very user friendly broad band match, however some transceivers may require an internal or external ATU to provide full power output.
