                                       New Antennas provide tactical maritime users with a high performance solution
                                       to broadband VHF communications. Utilizing technology designed for military and
                                       commercial applications, Digital Antenna delivers the latest antenna technology to
                                       the marine industry with their new, highly advanced Wide Band VHF Antennas.

                                       Featuring a tremendous bandwidth of 134 to 176 MHz, a nominal 6dBi gain and the
                                       ability to withstand continuous RF power up to 500 watts, the new antennas allow
                                       high quality communications across a normally hard to cover band. An exclusive
                                       patent pending electrical design with internal ground plane allows the antenna to
                                       maintain a low radiation pattern giving the antenna exceptional communication
                                       capability over a wide bandwidth.

                                       Designed to meet the military’s rigorous MIL-STD-810 environmental engineering
                                       testing as well as typical marine standards for high seas applications, the 992-MW
                                       and 992-MB antennas are built to endure environmentally harsh conditions.
