Sirio - Gain Master Verticale 5/8 CB e Bande10-12 metri

Description: Gain-Master™ is a high-tech 0.625λ fiberglass base station antenna covering the CB, 10m amateur bands. Completely computer designed using electromagnetic simulations to obtain maximum gain and optimize radiation pattern and bandwidth. . Designed with the most advanced technologies available, it is completely built in Italy using high quality materials. The new design of the radiating element works as a dipole fed at its centre, all RF currents on the radiator are in phase so the ground plane is not necessary. The coaxial coil at the base works as an RF-choke for excellent decoupling from the support pole and the power line. Built with telescopic fiberglass tubes, it is DC short circuited for the best protection against static discharges.
Gain-Master™ is the new gold standard in its antenna class.
