Start with the function: Yes—disconnect antennas before the storm arrives when the station’s design provides a safe external disconnect and storage path. Do not handle feed lines once lightning is nearby.
What the label leaves out
A loose indoor coax can still arc to equipment or people, and disconnection does not protect power, network, control, or grounding paths.
The mistake to avoid
Waiting for thunder before unplugging a cable puts the operator at the entry point during the highest-risk period.
A sound installation approach
Monitor weather, stop early, use an outside bonded disconnect or switch designed for the system, place conductors away from occupied equipment, unplug other services where safe, and leave the station alone.
System boundary
Use current manufacturer documentation, measured RF behavior, the building grounding system, and applicable electrical and lightning requirements. A ratio, DC continuity check, or inline protective device does not establish complete-system safety or efficiency.
