The EAGLE is the smallest antenna in the GAP product line. The Eagle weights less than 9 Kg and can be installed almost anywhere - at ground level, on a pole, on your roof or atop a tower. It is essentially a set of vertical dipoles - the optimum singular DX antenna! No traps, coils or transformers are used to achieve multiband operation in this antenna either.The EAGLE provides full coverage with VSWR < 2:1 on 40/20/17/15 and 12m; and approximately 500KHz on 10m without readjusting.If the band is wide open, you might work a VK with a coat hanger, but when conditions are less than perfect you want the highest efficiency the antenna can provide. The efficiency of the GAP Eagle is without equal. It has no traps, transformers or matching coils to rob transmitted or received power. For the highest S meter reading, choose a GAP Eagle.Three rigid counterpoises are required for operation (see picture) but no radials.
