Description

Shure UA840UA 840-UA Antenna Distribution

The Shure Model UA840 is an amplified, UHF Antenna Distribution System designed to expand a wireless microphone system by splitting one pair of antennas to multiple receivers. It also amplifies RF signals to compensate for insertion loss due to splitting signal power to multiple output ports. Each UA840 allows up to four receivers to use the same antennas. A CASCADE port allows connections to a fifth receiver or a second UA840.

Features:

  • Expandability - The UA840 UHF Antenna Distribution System is designed for large UHF wireless systems. Each unit allows up to four wireless receivers to use the same two antennas, and the cascade ports allow connection for up to five (5) more UA840’s, for a total of up to 20 UHF wireless receivers.
  • Compatibility - The UA840 is compatible with all wireless microphone receivers operating within a compatible frequency range (see UHF Carrier Frequency Ranges in the Specifications section).
  • CASCADE Ports - Two 50 Ω, BNC-type antenna CASCADE ports allow additional UA840 unit or a fifth wireless receiver. A large wireless system can use a single pair of antennas.
  • Power OUTPUT Port - Up to five (5) receivers can be daisy-chained via the Power OUTPUT ports to a single power source.
  • Low Noise and Intermodulation Distortion. The UA840 maintains clean signals with minimal distortion.
  • Insertion Loss Compensation - Whenever a signal is split to multiple output ports, there is a loss in signal strength. The UA840 amplifies signals to compensate, ensuring a strong signal to the receivers.
  • Front-Mounted Antennas - The UA840 comes with hardware to front-mount the antennas, if desire
