SIRIO - GAIN-MASTER HW - HALF-WAVE BASE STATION ANTENNA - FIBERGLASS SHELL - 27.2-30 MHz TUNEABLE - LENGHT m 5.56 - NO RADIALS
Gain-Master™ is a 1/2 λ high tech fiberglass base station antenna for wide band coverage from 10m amateur band to 11 meters CB band, whose design is derived from that of the taller 5/8 wave sister antenna.
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 radiating 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.
Gain-Master™ is the new reference standard in its class of antennas.
