SY Series: Sinclair’s Next-Generation Yagi Directional Antennas

Designed for superior performance and versatility, Sinclair’s new SY Series multi-element Yagi antennas fulfill a variety of applications. The SY350-SWBSNM(ABK) and SY450-SWBSNM(ABK) Series features a highly directional radiating pattern ideal for point-to-point communication applications. The SY Series is ideal for wideband systems as these antennas achieve superior performance over the entire 746-960 MHz and 380-512 MHz frequency bands, depending on the model. All elements in the SY Series are DC grounded for lightning protection. This series has been largely used in applications like Public safety, Utility, Cellular, Transit and Natural Resources. The SY350 and SY450 Series feature a seamless aluminum body, which is 360° fully welded for durability and enhanced electrical performance. These pre-assembled antennas can also be stacked for additional gain. The ABK models of the SY series are anodized to make their aluminum bodies corrosion-resistant for added durability with a sleek black finish. The fully sealed-driven element offers complete protection against humidity, acid rain, or salt spray. Since 1951, Sinclair’s legacy of sturdy antenna construction coupled with advanced engineering designs provides outstanding durability and superior performance in all weather conditions.
