RF diagnostics outside the lab
Field RF service work starts from the installed path rather than a controlled bench setup. The practical questions are whether the antenna, cable assembly, connector interface, enclosure, grounding and nearby RF environment still match the expected operating condition.
Typical checks in the field
Useful records include connector type, cable length, measured path loss, VSWR trend, reflected-power condition, antenna orientation, weather exposure, calibration state of portable instruments and any change made during service. Keeping these details with the fault record makes repeat visits and remote support more reliable.
