Was It Lightning Damage to a TV Antenna? | Envista Case Study

The initial case study examines a claim pertaining to lightning damage. The claimant, a broadcaster, reported elevated Voltage Standing Wave Ratio (VSWR), suggesting probable damage to their transmission line or antenna. The investigation revealed that the damage originated not from lightning, but from arcing due to poorly maintained sections of the line. The conclusion drawn was that subpar maintenance over time had resulted in the degradation of the overall broadcast system. After replacing the transmission line, the system resumed normal operations.
