Shure UA850 – 50 ft BNC Coaxial Antenna Extension Cable

Product Overview

The Shure UA850 is a 50-foot (15 m) BNC-to-BNC low-loss coaxial antenna extension cable for use with Shure UHF wireless systems operating below 1 GHz. Built on RG8X/U-type coaxial cable with 50 Ω impedance, the UA850 provides the signal path between remote antenna placements and rack-mounted wireless receivers, a standard requirement in commercial AV installations where antennas must be positioned away from the equipment rack for optimal coverage. It is a core infrastructure cable for UHF wireless system integration in commercial environments.

Product Description

In commercial AV installations — conference rooms, boardrooms, training facilities, and government spaces — wireless receivers are typically rack-mounted in equipment rooms or AV furniture, while antennas must be positioned at the room perimeter or ceiling for optimal coverage and RF line-of-sight to transmitters. The UA850 bridges this separation with 50 feet of low-loss 50 Ω coaxial cable, terminated with BNC connectors at both ends for direct connection to Shure receivers and antenna distribution systems. RG8X/U-type construction balances flexibility with low signal loss per foot, making it appropriate for typical commercial UHF antenna runs. Multiple UA850 cables can be used in systems with antenna distribution units such as the Shure UA845UWB Antenna Distribution System. The cable is rated for frequencies below 1 GHz and should not be used for 1.2 GHz+ band systems.

Key Features

• 50-Foot Low-Loss Coaxial Cable — Provides 50 ft (15 m) of antenna extension path using RG8X/U-type coaxial cable, balancing signal loss and cable flexibility for typical commercial UHF antenna runs.
• BNC-to-BNC Termination — Factory-terminated with BNC connectors at both ends for direct, secure connection to Shure wireless receivers, antenna distribution systems, and antenna hardware.
• 50 Ω Impedance — Matches the impedance of Shure UHF wireless system RF components, ensuring a proper signal path without impedance mismatch losses.
• Rated for Sub-1 GHz UHF Applications — Specified for use with Shure UHF wireless systems operating below 1 GHz, covering the majority of standard commercial wireless microphone frequency bands.
• Compatible with Shure Antenna Distribution Systems — Works with the UA845UWB and other Shure antenna distribution systems, enabling antenna feeds to be extended from centralized distribution hardware to remote antenna positions.
