AY-156-162: High-Gain Directional VHF Marine Band Yagi Antenna
The AY-156-162 is a high-performance directional Yagi antenna specifically designed for the 156–162 MHz Marine Band. Delivering a substantial 12 dBi gain, this antenna is engineered for long-range point-to-point communication, maritime safety systems, and base station applications. Its robust construction and high efficiency make it an ideal choice for GMDSS (Global Maritime Distress and Safety System) infrastructure, ensuring reliable links for search and rescue operations.
Design and Innovation
The AY-156-162 incorporates a unique feed system that acts as an integrated matching device, maintaining a consistently low VSWR across the entire 6 MHz bandwidth. This innovative approach eliminates the need for traditional folded dipoles, reducing potential points of failure and increasing overall antenna efficiency. The antenna is versatile by design, offering the choice of horizontal or vertical polarization and the option for either center or rear-end mounting to suit specific site requirements.
Fabrication and Marine-Grade Durability
To withstand the relentless corrosive nature of maritime environments, the antenna is fabricated using 6063T6 ultra-corrosion-resistant architectural aluminum alloy. The support boom is constructed from a 25.4mm square tube, while the radiating elements utilize 19mm round tubes for optimal structural integrity. All mounting hardware is made from Type 316 marine-grade stainless steel, and the entire assembly is finished with a high-quality powder coating to protect against UV radiation, salt spray, and extreme humidity.
Performance and Efficiency
With a 12 dBi gain and a Front-to-Back ratio of 16 dB, the AY-156-162 provides excellent signal directivity and interference rejection. It features a horizontal beam-width of 48 degrees and a vertical beam-width of 40 degrees, allowing for precise signal targeting. The antenna is factory-tuned to a VSWR of better than 1.5:1 and can handle up to 250 Watts of continuous RF power, making it suitable for high-demand maritime communication hubs.
