Lightning
While most amateur radio installations rarely suffer damage from lightning (even though they never
disconnect their equipment); the best protection is to disconnect electrical devices during storms.
The key to proper lightning survival is proper grounding of feedlines and equipment, and
maintaining integrity of shield connections. A proper installation improves lightning protection and
enhances weak-signal receiving performance. The
DXE-RLP-75FF
Lightning Protector, 75-ohm,
DC Pass, Type F Connectors is one optional device that could be used.
Consult lightning protection
and station grounding information in the ARRL handbooks, the National Association of
Broadcasters (NAB) handbook or other reliable sources.
