Sirio Antenna Sirio 2016 (26.4-28.2 Mhz) 5/8 Wave 3000 Watts Tunable 10M & CB Base Antenna

The most modern technology and the most advanced instruments have been used for realization of SIRIO 827, the new base antenna with remarkable characteristics. It is made of silicium magnesium aluminum tubes of big dimensions drawn and cemented on the surface to get the maximum strength of the main whip. The coil, made of enamelled copper wire of big section, has been specially planned in order to bear high powers. It adopts the exclusive System C.A.C.S. (coil auto-cooling system) which allows the auto-cooling by a finned support that keeps the coil hanging up allowing the air circulation. Engineered with the most advanced available technologies it is completely 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.
