This Shure UHF‑R 6‑Channel Wireless System in the H4 band configured with six UR1‑H4 bodypack transmitters, six UR2‑H4 handheld transmitters, a triple‑racked set of UR4D‑H4 dual receivers, two Shure active paddle antennas, a Shure UA845‑SWB antenna distribution amplifier, a Netgear GS105 gigabit network switch, and two mic stands provides a robust, scalable wireless platform designed for large venue productions, touring shows, corporate AV, and broadcast environments where RF reliability and multi‑channel coordination are essential. The UHF‑R platform offers a wide 60 MHz tuning bandwidth with support for up to 40 compatible systems per band, along with features such as Audio Reference Companding, which improves perceived audio quality by reducing artifacts common to analog wireless systems. The UR4D‑H4 receivers supply automatic frequency selection, group scanning, infrared transmitter sync, and true diversity reception for stable RF performance, with Ethernet connectivity allowing integration with Shure Wireless Workbench for systemwide frequency coordination, monitoring, and remote management—especially important when handling multiple simultaneous channels across several receivers.

The UR1 bodypacks and UR2 handheld transmitters provide rugged metal construction suited for touring and maintain solid performance within the H4 band’s allocated UHF frequencies, pairing reliably with the receivers for consistent transmission even in difficult RF spaces. To enhance system stability further, the two active Shure paddle antennas improve reception through directional gain and stronger resistance to interference compared with standard whip antennas. The inclusion of a Shure UA845‑SWB wideband antenna distribution amplifier ensures that all six channels receive strong, clean RF signals by splitting and amplifying antenna feeds across multiple receivers without signal degradation. A Netgear GS105 gigabit network switch ties the receivers together for streamlined network control, enabling synchronized scanning and frequency management through Wireless Workbench. This fully assembled H4‑band UHF‑R system provides a comprehensive, road‑ready wireless solution capable of delivering stable RF performance and clear audio across large stages and complex production environments.
