RF Venue CX-22
UHF Ceiling Antenna


RF Venue's CX-22 Antenna is an unobtrusive, near field antenna system designed to work with wireless microphones.  It attaches easily to any standard 2 ft x 2 ft ceiling tile with the included hardware kit and blends in easily to any boardroom, classroom, or other drop-ceiling environment.  Available with an optional junction box and in custom color-matched paint (contact your sales representative for more info), the CX-22 Antenna has similar interference-mitigation characteristics to RF Venue's RF Spotlight, but in a more install-friendly form factor.  It is particularly useful where many separate wireless systems are inter-operating across the facility and local field "spotlight" coverage is desired to maximize available spectrum and mitigate interference between rooms.
