New Hi-Tech Antenna for use on 26-28Mhz.
New base antenna from Sirio that gives great performance over 26-28Mhz covering both CB radio and 10 metre Amateur bands, and is designed by electromagnetic simulation to achieve the maximum gain and optimize the radiation pattern and bandwidth.
Engineered with the most available technology, manufactured in Italy from high quality materials.
The new design of the radiant element (patent pending), works like a central fed dipole, so all of the RF currents on the radiator are in phase and ground plane radials are not necessory. The co-axial coil at the bottom works like an RF choke for the optimum decoupling from the mast and feedline.
The Gain Master is made of telescopic fibreglass tubes, it is DC grounded for the best protection from static discharges. Sirio think it is the new reference standard in its class of antennas.
