The Sirio FLEX-LOG 4 is a capable, logarithmic-loaded CB mobile antenna engineered in Italy for CB 27MHz use. With 250W continuous power handling (750W short time CW), a tunable frequency range of 26.9–27.5 MHz, and a bandwidth of ≥1 MHz at SWR ≤2, it offers a significant step up in power and bandwidth over shorter whip antennas while remaining compact and easy to mount. Standing at 1260mm tall with a universal 3/8" thread mount, it fits a wide range of standard mobile antenna mounts. Constructed from copper, chromed brass, and fibreglass for durability and a clean finish.
