The ZM21-4GX High Gain 4G LTE Marine Fold Down Antenna is a high-performance omnidirectional solution designed to maximise mobile network coverage in the 700-788 MHz LTE band, delivering improved signal stability and extended reception range in coastal, offshore, and remote mobile environments. Engineered as a high-gain collinear antenna system, the ZM21-4GX is optimised for vessel-mounted and fixed-deck installations where reliable cellular connectivity is required for communications, tracking, telemetry, and data-driven applications. Its 8.1 dBi gain performance supports enhanced signal capture in low-coverage areas, making it suitable for offshore fringe reception and rural network extension scenarios. The 2.1m radiator is designed for efficient omnidirectional propagation while maintaining mechanical strength under marine wind loading and continuous vibration conditions. Rated for 20W power handling, the antenna integrates seamlessly into marine and light industrial LTE systems. Supplied with 4.5 metres of integrated coaxial cable and FME female termination, the ZM21-4GX is designed for straightforward installation and clean cable routing through vessel or structure entry points. Installation is supported via compatibility with fold-down mounting systems, including MM1 nylon and MM2 stainless steel marine-grade bases, allowing secure deployment with the flexibility of lowering the antenna when required for clearance or protection. For static roof/deck mounting we also offer the MM3 316 stainless steel flange mount.
