SIRIO 827
CB & 10 m Base Station Antenna
DESCRIPTION
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, hasbeenspeciallyplannedinordertobearhighpowers. ItadoptstheexclusivesystemC.A.C.S.(CoilAuto-CoolingSystem)which allowstheauto-coolingbyafinnedsupportthatkeepsthecoilhangingupallowingtheaircirculation.
