MC3-160

MC3-160: 3 dBi Marine Band Omnidirectional Fiberglass Collinear Antenna

The MC3-160 is a professional-grade, center-fed collinear antenna specifically engineered for the 156–162 MHz VHF Marine Band. Designed as a compact and highly reliable base station solution, it provides a stable 3 dBi gain and broad vertical coverage. Its ruggedized fiberglass construction makes it an essential tool for GMDSS (Global Maritime Distress and Safety System) equipment, enhancing maritime safety and search-and-rescue efficiency across the globe.

Design and Survivability

The MC3-160 is built to withstand the most aggressive offshore and coastal environments. It features a high-tech ruggedized fiberglass radome that protects the internal radiating elements from extreme UV radiation, acid rain, and heavy salt spray. Its compact 1.5-meter profile significantly reduces wind loading, allowing it to maintain structural integrity in wind speeds up to 200 Km/Hr. The antenna termination is strategically housed at the bottom of the assembly to ensure the connection remains completely weatherproof.

Precision Fabrication

This antenna utilizes a center-fed design, which is critical for eliminating radiation pattern distortion and ensuring a true 360-degree horizontal coverage. The internal structure consists of large-diameter high-quality brass radiating elements stacked vertically and fed in phase. The support pipe is manufactured from 6063T6 ultra-corrosion-resistant architectural aluminum, and all mounting hardware is made from Marine Grade Type 316 Stainless Steel to prevent rust and galvanic corrosion.

Optimized Performance

With a consistent 3 dBi gain and a wide vertical beam-width of 78 degrees, the MC3-160 ensures reliable communication with vessels even in choppy seas where pitch and roll might otherwise disrupt narrower signals. It features specialized stub matching for a smooth VSWR of 1.5:1 or better across the entire bandwidth. Boasting an impressive MTBF of 90,000 hours, this antenna is a low-maintenance, high-reliability solution for critical maritime radio links.
