Antenna Combiner for Four PSM 600 Systems 620-670Mhz Shure PA-Series UHF Antenna Combiners are designed to allow up to four PSM wireless transmitters to use a single antenna. The unit combines four PSM wireless transmitters to a single antenna, reducing stage clutter and improving intermodulation distortion performance. Features: • UHF operation • Up to four wireless transmitters can be combined into one transmitting antenna. • Low noise and intermodulation distortion. The PA Antenna Combiner maintains clean signals with minimal distortion. • Microstrip technology for signal combining and filtering. • Four push/pull amplifiers for improved linear performance. • Front-mounted antenna. The PA Antenna Combiner comes with hardware to front-mount the antenna, which allows for better radio transmission. • Dual rackmount hardware.
