SS58 base loaded
The shortest standard PRV arrangement for 40-10 m operation.
Portable resonant vertical system
Resonant performance you control at the operating site
Tune the antenna—not your expectations.
CHA PRV 2.0 is a field-tunable resonant vertical for operators who want low-SWR operation without relying on a wide-range antenna tuner. The adjustable MCC 2.0, SS58 whip, extension, and controlled artificial ground form a complete system that the operator tunes at the installed site.
Use the compact base-loaded or taller center-loaded arrangement from 40 through 10 meters, or reconfigure the supplied SS58 for the documented 6-meter vertical off-center-fed dipole. Optional MIL WHIP 2.0 and fully extended SS17 paths are guide-defined expansions; SS25 is not supported.
- Coverage40-6 m, configuration dependent
- ResonantLess than 2:1 SWR when tuned
- Included returnFour 12.5 ft banana-plug wires
- No SS25Not defined by the PRV guide

Documented ways to use this system
Each card describes a complete guide-controlled path. Connector fit alone does not create another supported configuration.
SS58 center loaded
Use one included SINGLE EXT, or the guide-defined two-extension option, to raise the loading coil.
6 m OCFD
Use the SS58 with the BLANK and without MCC or counterpoise wires as documented.
Tuning boundary: tune the completed installed antenna at low power. The SS17 is fully extended in the PRV/MCC path. Do not use SS25, and do not infer an electrical configuration from 3/8-24 thread fit.
