CHA MPAS 2.0 Configuration Guide: Parks on the Air (POTA)

For POTA, carry a fast vertical plan and a wire plan; choose between them after seeing the activation site, available supports, wind, and visitor traffic.

In plain language: For POTA, carry a fast vertical plan and a wire plan; choose between them after seeing the activation site, available supports, wind, and visitor traffic.

POTA rewards stations that get on the air without turning setup into the whole activation. MPAS 2.0 is useful because the operator can choose speed or a larger wire geometry from the same kit.

Build the documented shape

  • Use Manpack or Portable Vertical when time and footprint are tight.
  • Use the sloper or inverted V when a safe support can improve the operating opportunity.
  • Use Horizontal NVIS when the objective is a regional net rather than distant hunters.
  • Keep all wires, guys, and coax out of public paths.

Why an operator chooses it

The “best” park setup is the one that fits the site, survives the weather, and supports the contacts the operator wants before teardown time.

Read the site before opening the bag

Walk the footprint before unloading. Note trees, power lines, trails, picnic areas, vehicles, wind, and the direction of likely contacts.

Common ways this goes wrong

  • Choosing a wire layout before confirming legal and safe supports.
  • Blocking a trail with coax or counterpoise.
  • Skipping a backup vertical plan.
  • Assuming every park permits stakes or lines in trees.

Before you transmit

  • Confirm the exact radiator, matching unit, return path, feed line, and support arrangement.
  • Keep conductors and supports clear of power lines and uncontrolled public access.
  • Reproduce the guide dimensions before experimenting.
  • Inspect every connection and begin testing at low power.
  • Record geometry, band, tuner state, and the result before changing one variable.
Boundary: Park rules and site permission are outside the antenna manual and must be checked locally.
Use the current source before deployment.

This lesson explains the decision. The official guide controls assembly, ratings, configuration details, and safety.
