Optimised for 4G/ LTE networks operating in the 850 MHz band, the ZM21-CELLN supports voice, data, and telemetry applications across vessel-based communications, offshore infrastructure, and mobile installations requiring dependable long-range cellular performance. Its collinear design provides uniform 360-degree coverage, enhancing signal reception and transmission in areas where distance, terrain, or water-based propagation impacts network reliability.
Common applications include marine communications, vessel internet connectivity, onboard monitoring systems, coastal transport assets, and remote mobile broadband installations.
The antenna supports up to 30 W power handling and is supplied with a 5 m cable terminated in an FME female connector, with compatibility for standard marine RF system integrations. Installation requires a suitable fold-down mounting base such as MM1 nylon or MM2 stainless steel hardware, enabling flexible deployment on vessels or elevated structures.
ZCG Scalar recommends mounting the antenna as high as possible to maximise line-of-sight exposure and optimise omnidirectional performance in marine environments.
Combining high gain 4G performance, marine-grade construction suitability, and stable omnidirectional coverage, the ZM21-CELLN is a purpose-built solution for lower-band 4G connectivity in marine and coastal applications.
