Sinclair SY Series - Yagi Directional Antennas
January 3, 2019

The SY SERIES is Sinclair’s next-generation of yagi directional antennas. Designed for superior performance and versatility, Sinclair’s new SY Series 6-element Yagi antennas fulfill a variety of applications. The SY350-SWBSNM(ABK) andSY450-SWBSNM(ABK) feature 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.  Besides the corrosion-resistant anodized aluminum body for added durability and long life, the ABK models of the SY series are finished with an additional sleek black coating. 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 environmental conditions.
