Shure PA421BX 4-Channel Antenna Combiner for PSM Wireless Systems - 865-960 Megahertz
The PA821B active broadband antenna combiner streamlines the simultaneous operation of many PSM systems at a venue. The PA821B combines the RF outputs from up to four PSM transmitters into one RF output to feed a single transmit antenna. This provides significantly improved reception quality due to reduced intermodulation distortion and dropouts due to multipath interference. (Directly replaces PA421A.)
Features:
- Combines up to four PSM transmitters to a single antenna set for improved RF networking & reduced rack clutter.
- Wideband operation (865-960 Mhz)
- 4 Input LED signals (green when active; off when inactive)
- Quieter, temperature-sensitive fan for significant reductions in ambient unit noise and heat
- Daisy-chain up to 2 combiners with the expansion port.
- LED indicators for signal presence and signal overload
- Passive (non-powered) antenna combining*
