Availability:
The Sirio Gain-Master is a high tech fibreglass 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 fed 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 an 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.
Very please indeed, was recommended this antenna by a few people and it doesn’t disappoint. Easy to put together if you take your time, instructions could be a little better but you can still follow what’s there ok. It is a wieldy beast to put on the mast section on install don’t do this on a windy day. Less background noise, great quality antenna.
