The NEW GAIN MASTER by SIRIO is a high tech fiberglass base station antenna for CB and 10m amateur band. Engineered with the most advanced available technologies, it is completely manufactured in Italy with high quality materials. Completely designed by electromagnetic simulation to achieve the maximun gain and optimize the radiation pattern and bandwidth. The new design of the radiant element 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 an RF choke for optimum decoupling from mast and feeding line. Made of Fiberglass telescopic tubes, it is DC Grounded for the best protection from static discharges.
