Sirio 827 - Manual

DESCRIPTION
SPECIFICATIONS
The most modern technology and the most advanced instruments have been used for the realization of SIRIO 827, the new base
antenna with remarkable characteristics. It is made of Silicium Magnesium Aluminium tubes of big dimensions drawn and
cemented on the surface to get the maximum strenght 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.
