Cable and antenna analysis (CAT)

Fifty to sixty percent of microwave-link equipment issues are related to cables, antennas, and connectors. Degraded feeder lines cause poor coverage, link failures, and reduced sensitivity in the receive path. To maintain microwave link quality, it is critical to keep cable and antenna systems in good working condition. FieldFox is uniquely qualified to provide all the necessary measurements to troubleshoot and maintain these systems.
