Gain-Master

ä 

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-Master

is the new reference standard in its class of
