Why Choose the CELmar3-2 Marine VHF Antenna?
The CELmar3-2 is a strong choice where a higher gain VHF antenna is required for dependable communications across larger vessels, commercial craft and fixed coastal installations. Its 3 dBd gain and 2.70 metre length make it better suited to applications where increased antenna performance is preferred over a compact low-profile installation.
AC Antennas describes this model as a lightweight omnidirectional 3 dBd high gain antenna with excellent performance and dependability. The supplied 18m RG58C/U cable provides additional installation flexibility, especially where the antenna is mounted higher on a mast, wheelhouse, arch or shore-based structure.
The antenna uses brass radiating elements, fibreglass construction and AC Antennas’ reinforced crimped construction technology to provide a rugged build for demanding marine environments.
Marine VHF Installation & Mount Compatibility
The CELmar3-2 is fitted with a standard 1″-14 TPI female ferrule, making it compatible with many common marine antenna mounts and brackets. Due to its 2.70 metre length, the mounting location should provide suitable mechanical support and clear antenna separation from other onboard equipment.
Marine VHF Range Considerations
VHF communication range is strongly influenced by antenna height, installation position, vessel structure and cable quality. A high gain antenna such as the CELmar3-2 can support stronger VHF performance, but correct installation height and positioning remain critical for reliable real-world communication range.
