CHA PRV 2.0 Four-Counterpoise Configuration

CHA PRV 2.0 Four-Counterpoise Configuration is a complete-system decision: the return conductor, its connection point, and its deployed geometry all affect the installed antenna.

In plain language: CHA PRV 2.0 Four-Counterpoise Configuration is a complete-system decision: the return conductor, its connection point, and its deployed geometry all affect the installed antenna.

The wire on the ground is not a disposable accessory. It forms the other side of this unbalanced antenna and can decide whether the feed line remains a feed line or becomes part of the radiator.

The CHA PRV 2.0 is designed for the operator who wants a resonant 40–6 m antenna without carrying a separate antenna tuner. Its standard field system combines the MCC 2.0, SS58 whip, 27 in SINGLE EXT, CHA BLANK, PUCK HUB, four 12.5 ft counterpoise wires, choked coax, Band Keys, and a selected MPAS READY mount.

What matters in this configuration

  • The PUCK HUB accepts the supplied banana-plug counterpoises. Their count and length change by band. The guide warns that too many or overly long counterpoises can leave a shallow SWR dip even when resonance is nearby.
  • Route the return conductors where people will not trip over them and where nearby metal will not quietly become part of the system.
  • When comparing two layouts, preserve band, radiator, feed line, choke position, analyzer reference plane, and site conditions.

Why this choice matters

CHA PRV 2.0 is a compact, field-tunable resonant vertical system built around the continuously adjustable MCC 2.0 loading coil. The useful result comes from the complete documented system rather than any one threaded component.

The parts that make it a complete antenna

  • CHA MCC 2.0 continuously adjustable loading coil
  • CHA SS58 telescoping whip and 27 in CHA SINGLE EXT
  • CHA BLANK feed point and CHA PUCK HUB
  • Four 12.5 ft banana-plug counterpoise wires, winders, and tent stakes
  • 12 ft RG-58 coax with an integrated RF choke
  • Band Keys, tactical storage bag, CHA SS INSULATOR, and the selected mount option

Use the result in the field

Record the exact radiator, loading or feed-point hardware, return system, mount, feed line, band, dimensions, and final measurement. Repeatability is more valuable than a one-time low SWR reading.

Before you transmit

  • Confirm the exact radiator and whether the MCC 2.0 is base loaded, center loaded, or removed for the 6 m OCFD.
  • Use the documented counterpoise count and starting length for the selected band.
  • Keep the supplied feed-line choke in the coax path.
  • Set the MCC 2.0 from the guide or Band Key, then fine-tune the installed antenna.
  • Inspect every mechanical and RF connection before applying operating power.
Boundary: The current guide documents SS58, MIL WHIP, and SS17 MCC 2.0 configurations. It does not document SS25, so connector fit must not be presented as approval.
Use the current source before deployment.
