The ClearOne 910-6005-008 Wireless Extension Antenna Kit is a hardware set for professional wireless microphone systems, specifically tuned for the M550 RF band (537–563 MHz). It is designed to extend the range and improve the signal quality of compatible ClearOne wireless microphone receivers, particularly in large venues or areas with obstructions. The kit is intended for ceiling mounting and includes a pair of antennas and two 25-foot (7.62m) plenum-rated RG58 cables. 

ClearOne's antenna kits are a turnkey solution for wireless microphone installations, removing the guesswork involved in selecting and terminating cables. The 910-6005-008 kit is designed to improve radio frequency (RF) reception by allowing the antennas to be placed in an optimal location, such as in the line of sight of the transmitters and away from metal fixtures. The included plenum-rated cables have a special, fire-resistant coating suitable for use in air plenum spaces, and they are cut to length, terminated, and tested by ClearOne to ensure proper performance. The antennas are phantom-powered directly from the wireless receiver, eliminating the need for an external power source.
