1.5 Quick reference to cable capacity and distance
Clear-Com recommends Belden 9207 for fixed installation, and Belden 9463F for portable installations.
Tip: The attenuation of a cable increases with distance, and this can impact audio quality. If your priority is
audio quality, experiment with attaching one or two fewer devices to each line. For in-depth cabling advice,
contact your Clear-Com representative.
