In plain language: When an MPAS READY system puts RF on the coax, radio, or operator, restore the documented radiator, return path, choke placement, and cable route before adding random suppression.
Why this matters in a Chameleon system
SWR that changes when coax moves, RF feedback, device resets, and touch-sensitive receive noise identify an unintended current path—not automatically a defective antenna.
Build or diagnose it this way
- Return to the exact documented configuration.
- Inspect counterpoise or radial attachment and spread.
- Confirm whether the selected feed line already includes a choke.
- Test at low power while changing one variable.
Wrong turns to avoid
- Adding a second choke without diagnosis.
- Assuming the vehicle, tripod, or soil is the return path.
- Tuning around a loose connector or missing counterpoise.
