8’ WIDE BAND VHF ANTENNAS 6dB GAIN FOR GOVERNMENT, COMMERCIAL AND RECREATIONAL APPLICATIONS NEW 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. Features: • Lifetime limited warranty • Broadband 134-176 MHz • Withstands continuous RF power up to 500 watts • Aircraft grade aluminum ferrule • Completely sealed • High performance 6dBi gain • Sleek mono-color design 900 Series: 992-MW | 992-MB 8’ WHITE 8’ BLACK 992-MW 992-MB Mount: Standard 1” – 14 threaded base. Connector: Mini-UHF female connector and PL-259 adapter. Cable: Includes 20’ exclusive low-loss, tinned braid, foil shielded, UV stable DA195 Ultra-Flex marine cable. Made in the USA, tested and tuned by hand for maximum performance, quality and durability.
