Sirio's new Gain Master HW (Half Wave) is a fiberglass omnidirectional base station antenna for 10m and 11m amateur bands and is made up of telescopic fiberglass tubes.

Engineered with the most advanced technologies it is completely manufactured in Italy, with high-quality materials.

The design of the radiant element works like a centrally fed dipole so all RF currents on the radiator are in phase so the ground plane radials are not necessary.

The coaxial coil at the bottom works like RF - choke for the optimum decoupling from the mast and feeding line.
