SY3 Directional CB Antenna 26-30 MHz
The SIRIO SY27-3 is a very strong yet lightweight antenna with high gain. Well-built, it provides great performance on 26.9-27.5 MHz. The SY27-3 is easily adjustable to cover up to 29 MHz in the 10-meter amateur band. The 3-element Yagi beam antenna works on the 27 MHz band with Gamma System Match. It is entirely made of anticorodal aluminum and comes with a large section boom and a steel bracket for mounting on a support mast. The fixed part with the quick mounting system is made of die-cast metal for maximum strength. Each element is provided with polyethylene sleeve joints for perfect waterproofing. It comes equipped with a female UHF connector.
