Make the complete-system decision: High SWR is a symptom. Restore the exact recipe, verify radiator and return geometry, inspect every connection, confirm the measurement plane, then change one variable at a time.

How to use this guidance

Return to a known guide configuration before diagnosing. Confirm the exact mount, base, radiator, return, feed line, adapters, tuner state, and installed geometry, then change one item per test.

The boundary that prevents mistakes

Do not infer compatibility from a shared connector, thread, diameter, product family, or a visually similar installation. Do not add a complete kit as if it were one component inside another system.

Use this field sequence

Define the job and site, select one named configuration, inventory every required group, read its current guides, build in documented order, verify mechanically and electrically, operate within limits, and record the final setup.

Source boundary

MPAS READY Product Guide 250725, current individual product guides, and the controlled Chameleon System Builder. Exact documented recipes control.
