Start with the decision: MCC 2.0 trades manual setup and narrower resonant bandwidth for a deliberate loaded-vertical current path; compare it with broadband HYBRID systems by complete band-change time, tuner need, return loss, efficiency, and footprint.
What changes the result
The exact MCC recipe controls whip type, coil location, feed point, SS INSULATOR, mount, feed line, artificial RF return, initial setting, final tuning, power, and support.
The mistake to avoid
SS25 is not documented with MCC 2.0/PRV 2.0. A 3/8-24 fit, tuner match, or remembered coil position does not authorize a new recipe.
Use this practical sequence
Choose one documented build, assemble and inspect it with RF removed, deploy its exact return, sweep broadly at low power, make one adjustment at a time, and record the final installed setting.
