Gain-Masterä is a 0.625
antenna for CB and 10m 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 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-Masterä is the new reference standard in its class of
antennas.
