Description

These units may show signs of heavy wear but are in good working condition. The Shure Model UA845US is an amplified, UHF antenna distribution system designed to expand a wireless microphone setup by splitting one pair of antennas to multiple Shure UR4 or Shure ULX4 wireless receivers. By distributing RF from a single antenna pair to multiple receivers, it helps streamline rack builds and reduce antenna clutter in multi-channel installations. The UA845 also amplifies RF signals to compensate for insertion loss caused by splitting signal power to multiple output connectors, helping maintain reliable reception across connected receivers. Each UA845 allows up to four receivers to use the same antennas, with a cascade port available for linking additional distribution as your system grows. System Fit and Everyday Use Built for UHF operation in the US 500 to 900 MHz carrier frequency range, the UA845US is a practical choice for venues, houses of worship, corporate AV, and touring racks where several wireless channels need consistent RF distribution from a shared antenna pair. Key Specifications Carrier Frequency Range (US): 500 to 900 MHz Connector Type: BNC-type x4 Gain Control: 3 dB typical, 0 dB to 3.5 dB from antenna input (Output ports 1 to 4) / 1 dB typical, -1.6 dB to +1.8 dB from antenna input (Cascade port) Impedance: 50 ohms Dimensions (H x W x D): 1.75 x 19 x 11.63 in (44.5 x 482.6 x 295.3 mm) Weight: 7 lbs, 5 oz (3.32 kg)
