Digital Antenna 992-MB-S 8' Wide-Band VHF/AIS Antenna; 6 dB Gain – Black
Wide-Band VHF / AIS Marine Antenna
6 dBi Gain
Built with technology proven in military and commercial use, the 992-MB-S brings high-performance broadband VHF communications to demanding marine environments. Covering a wide 134–176 MHz bandwidth with a nominal 6 dBi gain, it supports AIS, marine VHF, NOAA weather, amateur radio, land mobile, and VHF SATCOM services for reliable long-range connectivity.
An exclusive patent-pending internal ground plane preserves a low radiation pattern across the band for exceptional wide-band performance. Designed to meet rigorous MIL-STD-810 environmental standards, this antenna is fully sealed and finished for durability. Each unit is hand-assembled, tuned, and tested in the USA for maximum quality and reliability.
