The AC Antennas CX4-3 (traditionally manufactured under AC Marine) is an industry-standard, omnidirectional fiberglass VHF antenna. It is widely recognized across the commercial maritime and fishing industries for its exceptional build quality and longevity in harsh saltwater environments.
Featuring a collinear 0 dBd (3 dBi) gain design, it provides an stable, balanced radiation pattern that ensures reliable line-of-sight communication even when the vessel is pitching or rolling heavily.
Premium Materials: The radome is constructed from premium-grade, heavy-wall white fiberglass finished with a UV-resistant polyurethane coating to prevent yellowing and fiber splintering.
Solid Internal Components: Unlike budget marine antennas that use loose coaxial cable internally, the CX4-3 features solid brass and copper internal elements to maintain structural stability under high vibration.
Base Hardware: The mounting ferrule is made from solid, chrome-plated brass with standard 1″-14 threads, making it compatible with generic marine mounts.
