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. Key Features 1000W continuous power handling (CW) 3000W short time power handling (CW) Gain: 8.5 dBd / 10.65 dBi — exceptional directional performance Tunable frequency range: 26.5–30 MHz Compatible with CB 27MHz & 10-metre amateur radio Bandwidth: ≥1.2 MHz @ SWR ≤2 3-element Yagi directional design Linear horizontal polarisation DC-grounded metal parts with capacitive inner conductor coupling On-mast mounting SO-239 (UHF-Female) connector Dimensions: 5942 x 2710 x 100 mm / 19.49 x 8.89 x 0.33 ft Made in Italy by Sirio Technical Specifications Type: 3-element Yagi beam antenna Radiation: Directional Polarisation: Linear horizontal Frequency range: 26.5–30 MHz (tunable) Systems: CB 27MHz / 10m amateur (HAM) Gain: 8.5 dBd / 10.65 dBi Bandwidth: ≥1.2 MHz @ SWR ≤2 Max power: 3000W peak (CW short time) | 1000W continuous (CW) Connector: SO-239 (UHF-Female) Dimensions: 5942 x 2710 x 100 mm Mounting: On-mast Construction: DC-grounded metal parts, capacitively coupled inner conductor Country of origin: Italy
