Sirio Gain Master 5/8

€ 199,30

Gain-Master™ is a 5/8 lambda high tech fiberglass base station 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.


Delivery only in BeNeLux !
