More info



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

The new design of the radiant element (Patent Pending) 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.

Made of telescopic fiberglass tubes, it is DC-grounded for the best protection from static discharges.

Gain-Master™ is the new reference standard in its class of antennas.
