The Sirio 2016 is a high-power, 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 26.4–28.2 MHz, a bandwidth of ≥2.1 MHz at SWR ≤2, and a gain of 1.3 dBd (3.45 dBi), it delivers excellent range and signal strength from your base installation. Standing at 6100mm (20.01ft) tall and designed for on-mast mounting, it's constructed from aluminium, copper, galvanised steel, and nylon for robust, long-lasting outdoor performance.
