Sirio Gainmaster 1/2 golf SI 2113120.00

FEATURES, FUNCTIONS AND SPECIFICATIONS:

Gain-Master HW is a HALF WAVE high tech fiberglass base station antenna for 10m to 11m amateur band made of telescopic fiberglass tubes.

Engineered with the most advanced available technologies it is completly manufactured in Italy with high quality materials.

The design of the radiant element works like a central feeded dipole so all RF currents on the radiator are in-phase and the ground plane radials are not necessary. The coaxial coil at the bottom works like RF-choke for the optimum decoupling from mast and feeding line.
