Sirio Gain-Master 5/8

The Sirio Gain-Master is a High Tech fiberglass base antenna suitable for 27MC (CB radio) and 10 meter amateur band.

The Gain-Master is designed to get the maximum gain (amplification) obtainable for a 27mc base antenna.

The antenna is manufactured with the most advanced technology from Italy with high quality materials. The new design of the radiant elements ( patent ) works with a central dipole so that all RF parts of the antenna are in phase and no side radials are needed.
The coaxial coil at the bottom of the antenna operates for optimal connection between the antenna and the coaxial cable.
The Sirio Gain-Master is made of fiberglass parts and is grounded against high voltage.
