The QPT-RF series of Pan & Tilt Positioners employ RF Rotary Joint technology for management of radio frequency signals. These rugged antenna positioners support a wide range of antenna sizes, frequency bands and one or two isolated channels of RF pass-through signals. Auxiliary sensor loads, such as visible and/or thermal cameras, can be mounted alongside the antenna and are completely supported. Essential for applications including: UAV tracking/ telemetry, satellite communications, radar, GPS and many others.

All RF, video, power and control data cables are pass-through to eliminate cables in motion with the Pan & Tilt making cable management simple, neat, and safe. IP, RS-232 & RS-422, Pelco D Extended, Serial control of the Pan & Tilt and sensors are standard. Serial data and lens controls provide plug-and-play camera load interfaces.
