The ZM21-UHF Marine UHF Antenna by ZCG Scalar is a high-performance, custom-built UHF communication antenna designed specifically for use on commercial and recreational vessels. Each antenna is precision tuned to your specified 1.5% UHF bandwidth at the time of order, ensuring maximum efficiency and reliable coverage across your desired UHF radio frequency range. This tailored approach ensures strong, uninterrupted signal performance in marine environments.
Supplied with 4.5 metres of RG58 marine-grade coaxial cable, the ZM21-UHF also includes a UHF PL-259 male connector, provided loose to allow for secure and seamless installation after cable routing. This makes it ideal for a wide range of vessel communication systems, offering both performance and flexibility.

To suit your mounting requirements, the ZM21-UHF is compatible with either the MM1 white nylon fold-down base or MM2 stainless steel fold-down base, sold separately. These options provide a durable and corrosion-resistant solution for secure installation in harsh marine environments.
For the best signal quality and true omni-directional UHF antenna performance, ZCG strongly recommends installing the ZM21-UHF as high as possible on your vessel or structure. Elevated mounting supports broad 360-degree UHF coverage and improved marine radio transmission range.
