Description

Gain-Master™ is a 0.625 high tech fiberglass
base station antenna for wide band antenna from 10m to 12m*
amateur band

Completely designed by electromagnetic simulation to achieve the
maximum gain and optimize the radiation pattern and bandwidth.

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

The new design of the radiant element (Patent Pending) works
like a central feed 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.
