Sirio Yagi 3 (SY-3) CB & 10m Ham Beam Antenna 1000W Continuous, 8.5dBd Gain, Tunable 26.5-30MHz

The Sirio Yagi 3 (SY-3) is a high-gain, 3-element Yagi beam antenna engineered in Italy for CB 27MHz and 10-metre amateur radio use. With a massive 8.5 dBd (10.65 dBi) gain, 1000W continuous power handling (3000W short time CW), a tunable frequency range of 26.5–30 MHz, and a bandwidth of ≥1.2 MHz at SWR ≤2, it's the antenna of choice for operators who demand maximum directional performance and DX range. All metal parts are DC-grounded with capacitive coupling on the inner conductor for excellent lightning protection. Designed for on-mast mounting, it measures 5942 x 2710 mm and delivers outstanding front-to-back ratio and signal focus.
