The Sirio New Tornado 2024 is a powerful, 5/8λ ground plane base station antenna engineered in Italy for CB 27MHz and 10-metre amateur radio use. With 1000W continuous power handling (3000W short time CW), a tunable frequency range of 27–30 MHz, a bandwidth of ≥1.3 MHz at SWR ≤2, and a gain of 1.2 dBd (3.35 dBi), it's a serious performer for any base station setup. Standing at an impressive 7230mm (23.72ft) tall and designed for on-mast mounting, the 2024 version is built from aluminium, brass, galvanised steel, and UV-stabilised thermoplastic for outstanding durability in all weather conditions.
