What the operator is controlling
Look for abrasion, kinks, insulation cuts, corrosion, loose hardware, stretched line, dirt inside connectors, water exposure, and changed strain relief. Clean and dry the system before storage.
Where people get into trouble
A wire can still show continuity while a damaged connector, intermittent braid, wet assembly, or changed geometry creates unstable RF behavior. Visual and electrical checks belong together.
A repeatable field method
Compare a low-power analyzer sweep with the known-good baseline in the same geometry, isolate any change one component at a time, replace damaged parts, and never transmit into a questionable connection.
Follow the current guide for the exact CHA LEFS model, radiator, feed assembly, geometry, supports, and operating limits. A family name or mechanical fit does not establish electrical compatibility.
