In plain language: Inspect a portable feed line before and after every deployment; inspect permanent lines after severe weather, seasonal change, mechanical work, or any unexplained station change.
Why an operator notices it
Coax usually fails by accumulation: one crushed section, one wet connector, one repeated bend, one loose adapter. A short inspection catches those failures before RF turns them into heat or arcing.
Decisions that matter
- Set inspection frequency by movement, exposure, connector count, and consequence of failure.
- Retire questionable portable cables from critical kits until tested.
- Keep a known-good reference line for substitution.
A useful field check
- Look and feel along the jacket.
- Inspect pins, threads, seals, strain relief, and labeling.
- Measure continuity and RF behavior when visual inspection is not enough.
Common wrong turns
- Checking continuity only.
- Leaving damaged cable in the kit “for receive.”
- Assuming a cable is dry because the outside is dry.
Technical foundation
This lesson translates established transmission-line and antenna practice into a field decision. Use the current equipment datasheet and Chameleon product guide for changing loss, power, connector, installation, and compatibility limits.
