Covert Monitoring Antenna


The OMNI-A0199 is a covert, ultra-wideband antenna system designed for wideband frequency spectrum monitoring and is based on the successful OMNI-A0082 antenna. Band A covers 20 to 200 MHz, band B covers 100 to 700 MHz, band C is a highefficiency wideband 500 to 3000 MHz antenna and band D covers 850 to 6000 MHz. There is space available inside the roof box to mount small receiver systems.brThe OMNI-A0199 has an excellent omni-directional radiation pattern which provides 360° performance, and covers a 300:1 frequency range without significant elevation break-up. The low visual profile avoids drawing attention to the vehicle on which it is fitted.
