The ZM21-VHF Marine VHF Antenna, proudly manufactured by ZCG Scalar, is a compact and durable solution for marine vessel VHF communications within the 156-162 MHz frequency range. Designed for performance in a shorter overall length, the ZM21-VHF is ideal for vessels requiring a lower-profile antenna without compromising signal quality.
This collinear VHF antenna supports multiple mounting options for flexible installation. It is compatible with the MM1 white nylon fold-down base or the MM2 stainless steel fold-down base, both available separately. For fixed mast installations, the ZM21-VHF can also be mounted using a MMA mast mount adaptor in combination with 2 x EB1-SS stainless steel parallel mount clamps, offering robust support in demanding marine environments.

ZCG Scalar recommends installing the ZM21-VHF as high as possible on your vessel or fixed structure to achieve a true omni-directional radiation pattern, ensuring consistent 360-degree VHF coverage for vessel-to-vessel and vessel-to-shore communication.
During transportation, the ZM21-VHF should be oriented flat to avoid contact with overhead obstacles such as powerlines, trees, or bridges. For optimal performance, the antenna must be positioned vertically while in operation to maintain its stated performance specifications.
The ZM21-VHF is a trusted choice for mariners who require a reliable, space-efficient VHF antenna solution built to perform in real-world conditions.
