The Sirio Performer 5000 3/8" (No Shaft) is a high-power trucker-style CB and 10m HAM mobile antenna engineered in Italy. With an impressive 1500W continuous power handling (5000W short time CW), a tunable frequency range of 27–30 MHz, and a bandwidth of ≥2.6 MHz at SWR ≤2, it's built for serious operators who demand maximum performance from their mobile installation. This is the no-shaft version — ideal for use with your own existing shaft or spring, or where a shorter overall profile is preferred. Standing at 2020mm (6.63ft) with a universal 3/8" thread mount, it fits a wide range of standard trucker and mobile antenna mounts. Constructed from copper, chromed brass, stainless steel 17/7 PH, and UV-stabilised thermoplastic for outstanding durability.
