AC7-156-162: High-Gain VHF Marine Band Fiberglass Collinear Antenna
The AC7-156-162 is a professional-grade, high-gain omni-directional antenna specifically engineered for the 156–162 MHz Marine Band. Built for long-range reliability, this collinear antenna delivers a potent 7.5 dBi gain, making it an essential component for shore-based maritime stations, port authorities, and GMDSS communication setups. Its center-fed design ensures a clean horizontal radiation pattern, providing stable 360-degree coverage across the maritime landscape.
Design and Durability
The AC7-156-162 is designed to withstand the most aggressive maritime environments. It features a high-tech ruggedized fiberglass radome that protects the internal radiating elements from UV radiation, heavy spray, and extreme temperatures. To ensure easy logistics and lower shipping costs, the antenna is supplied in two segments that thread together with a high-precision system designed to prevent RF inter-modulation. The antenna termination is strategically enclosed at the bottom of the support pipe to ensure the connection remains completely dry and protected from the elements.
Precision Fabrication
Constructed using high-class brass radiating elements and 6063T6 architectural-grade aluminum alloy for the support pipe, this antenna is built for longevity. The radiating elements are vertically stacked and fed in phase, ensuring maximum signal concentration at the horizon with a 28-degree vertical beam-width. All mounting hardware is made from marine-grade Type 316 stainless steel, providing the highest level of protection against salt-fog corrosion and acidic coastal air.
High-Efficiency Performance
Performance is defined by a consistent 7.5 dBi gain and a low VSWR (better than 1.5:1) across the 6 MHz bandwidth. The use of specialized stub matching ensures that the gain remains constant, providing reliable links for GMDSS (Global Maritime Distress and Safety System) equipment. With a power handling capacity of 150 Watts, the AC7-156-162 is optimized to enhance maritime safety, facilitating clear communication for rescuing distressed ships, boats, and aircraft even in 100% humidity environments.
