How to Perform a Distance-to-Fault (DTF) Testing on RF Cables & Antennas 

Distance-to-Fault (DTF) testing helps RF technicians locate cable damage, connector problems, moisture ingress, and impedance mismatches before they cause system failures. By identifying the exact distance to a fault, technicians can troubleshoot faster, reduce downtime, and avoid unnecessary cable replacement.
