Sirio FLEX-LOG 3 CB Mobile Antenna 300W Peak, Tunable 26.9-27.5MHz, 3/8" Thread

The Sirio FLEX-LOG 3 is a compact, logarithmic-loaded CB mobile antenna engineered in Italy for CB 27MHz use. With 100W continuous power handling (300W short time CW), a tunable frequency range of 26.9–27.5 MHz, and a bandwidth of ≥600 kHz at SWR ≤2, it's the perfect choice for operators who need a lightweight, low-profile antenna without compromising on performance. Standing at just 900mm tall and featuring 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.
