Sirio ML 145 Inox CB & 10m Mobile Antenna 900W Continuous, Tunable 27-28.5MHz

The Sirio ML 145 Inox is a robust, base-loaded mobile antenna engineered in Italy for CB 27MHz and 10-metre amateur radio use. With 300W continuous power handling (900W short time CW), a tunable frequency range of 27–28.5 MHz, and a bandwidth of ≥1.34 MHz at SWR ≤2, it delivers reliable omnidirectional performance for everyday mobile operation. The Inox designation reflects its stainless steel 17/7 PH construction — offering superior corrosion resistance compared to standard mobile antennas, making it an excellent choice for coastal, marine, or harsh-environment use. Standing at 1420mm (4.66ft) with an on-connector mount for quick, tool-free installation, it's built from copper, brass, stainless steel 17/7 PH, and nylon.
