SHURE 舒尔 PA765 天线组合器
发布时间：2010-12-27编辑：DanceSmile阅读（）
四至一PSM天线组合器，适用于所有舒尔P4T、P6T、P7T和P9T 发射机（800-870 MHz）。
描述：
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.
功能：
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. The PA Antenna Combiner comes with hardware so that it can be rackmounted with another PA Antenna Combiner or PSM Transmitter into a single rack space.
