Overview

The Shure UA825 is a 25-foot coaxial extension cable designed specifically for extending the distance between Shure UHF wireless receivers and their remote antennas. Built with RG8X/U coaxial cable and terminated with BNC male connectors on both ends, it provides a reliable, low-loss signal path that maintains the performance integrity of professional wireless microphone systems. The RG8X cable type offers a favorable compromise between the low attenuation of heavier RG8 cable and the flexibility of thinner RG58, making it practical to route through venues while keeping signal degradation to a minimum.

In professional audio applications, antenna placement is critical for reliable wireless microphone and in-ear monitor performance. The UA825 allows engineers to position antennas in optimal locations — elevated, in line of sight with transmitters, or away from sources of RF interference — while keeping the receiver rack in a convenient backstage or front-of-house location. The secure BNC twist-lock connectors prevent accidental disconnection during performances, and the Shure-manufactured construction ensures proper 50-ohm impedance matching with Shure's UHF wireless ecosystem. For installations requiring runs longer than 25 feet, Shure offers the UA850 (50-foot) variant, or users can incorporate antenna distribution amplifiers to compensate for additional cable loss.

Pros & Cons

👍 Pros

  • RG8X coaxial construction provides lower signal attenuation than thinner cable types over the 25-foot run.
  • BNC connectors on both ends ensure a secure, twist-lock connection that resists accidental disconnection during events.
  • Shure-manufactured cable guarantees impedance matching and signal integrity with Shure UHF wireless systems.
  • 25-foot length provides meaningful reach for positioning remote antennas away from receivers in professional venue setups.

👎 Cons

  • At 25 feet, the cable only suits moderate-distance antenna relocation; longer venue runs will require additional cables or amplification.
  • RG8X is thicker and less flexible than thinner coax options, which can make routing through tight spaces more difficult.
  • Single-purpose cable works only for BNC-connected UHF antenna systems, with no broader audio or video application.
  • No built-in signal amplification means signal loss, while low, is still present and cumulative if multiple cables are used.

Frequently Asked Questions

The Shure UA825 is designed for use with Shure UHF wireless microphone systems that use BNC-connected remote antennas, such as the UR4, ULXD4, and similar receivers.
While physically possible, daisy-chaining extension cables increases signal loss at each connection point. Shure recommends using a single cable of the appropriate length or an antenna distribution amplifier for longer distances.
RG8X offers lower signal loss per foot compared to thinner RG58 cable, which is important for maintaining wireless signal strength over a 25-foot run. It provides a better balance of performance and flexibility than either RG58 or the thicker RG8.
This is a passive coaxial extension cable. If your setup uses active antenna components that require DC power, consult your system documentation to confirm compatibility.
The UA825 uses standard BNC male connectors on both ends, designed to connect between a Shure receiver's BNC antenna output and a remote antenna's BNC connector.
