Sirio 827 (26.4 - 28.4 Mhz) Tunable 10m & CB Base Antenna

The Sirio 827 base antenna is one of the most respected antennas around. High performance comes as standard and the 827 will let you transmit much much further than most conventional antennas, the build quality is superb, will give many years of service, and ideal also for amateur use on the very popular 10m (28Mhz) band too. The most modern technology and the most advanced instruments have been used for realization of SIRIO 827, the new base antenna with remarkable characteristics. I is made of Silicium Magnesium Aluminium 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.
