Digital Antenna 992-MB-S 8ft Wide-Band VHF/AIS Marine Antenna 6dB Black

The Digital Antenna 992-MB-S is an 8-foot wide-band VHF/AIS antenna engineered for land and marine use across government, commercial, and recreational applications. Built on technology originally developed for military and commercial platforms, it delivers high-performance broadband VHF communications across a frequency range that is traditionally difficult to cover.

An exclusive patent-pending internal ground plane design allows the antenna to sustain a low radiation pattern across the full bandwidth, maximizing signal quality and range. The 992-MB-S meets the military's rigorous MIL-STD-810 environmental engineering standards as well as marine standards for high-seas use, making it exceptionally durable in harsh conditions. Every unit is hand-assembled, tuned, and tested in the USA.
