The Shure UA850 is a high-quality coaxial extension cable designed to facilitate optimal antenna placement in professional wireless microphone and in-ear monitor systems. This cable allows system technicians to remotely position antennas away from equipment racks and potential sources of RF interference, a critical practice for maximizing signal strength and system reliability. Constructed with a low-loss dielectric core and effective shielding, the UA850 is engineered to preserve RF signal integrity over its length with minimal attenuation. By maintaining signal quality over distance, it ensures that the clean signal captured by a strategically placed antenna is delivered effectively to the receiver or antenna distribution system.

The cable is terminated with standard BNC connectors, the industry-preferred interface for professional RF applications, ensuring secure and reliable connections to antennas, splitters, and receivers. Its durable outer jacket is built to withstand the physical demands of both permanent installations and the rigors of touring. Available in various standard lengths, the UA850 enables flexible system design, allowing antennas to be mounted in ideal locations such as above a stage, within a ceiling, or along a proscenium arch. This capability is fundamental to achieving wide, consistent coverage and minimizing dead spots in a venue.

For audio engineers and system integrators, the UA850 is an essential infrastructure component. It transforms a wireless system from one constrained by the short antenna cables of individual receivers into a professionally distributed network. Using such low-loss extension cables is a best practice that directly contributes to fewer dropouts, extended operational range, and overall stability, especially in environments with many simultaneous wireless channels or challenging RF conditions.
