Stay connected and safe at sea with the ZM21-70 Marine Deck Mount Antenna, proudly manufactured by ZCG Scalar. Specifically tuned for peak performance on 70 MHz band, this antenna is built to deliver clear, reliable marine communication when you need it most. Whether you're operating a recreational vessel, a government patrol craft, or a commercial marine platform, the ZM21-70 provides strong, omnidirectional signal coverage to ensure your voice is heard. Its durable construction and precision tuning make it ideal for both regular communication and emergency broadcast requirements. To protect your signal integrity over time, ZCG strongly recommends sealing all terminations with butyl rubber self-amalgamating tape and a final layer of UV-resistant PVC tape. This ensures waterproof protection and prevents any moisture damage to your connections in challenging marine conditions. For best performance, the ZM21-70 should be kept in a vertical position during use. While transporting your vessel, always lay the antenna flat to avoid contact with low-hanging hazards like powerlines or bridge structures.
