In plain language: The MPAS Lite Telescoping Vertical is the five-minute, small-footprint configuration: HYBRID base, SS17 or documented optional SS25, spike, choked coax, and the specified counterpoise.

This is the configuration to learn first because it can be deployed without finding an overhead wire support.

Build the documented shape

  • Drive the spike approximately halfway into suitable ground with a plastic or rubber mallet.
  • Install the matching unit and whip by hand.
  • Unwind and route the counterpoise from the documented connection.
  • Connect the choked coax and perform a low-power test.

Why an operator chooses it

The vertical gives omnidirectional short- to medium-range opportunity and packs down quickly. The optional counterpoise kit can provide a more developed radial system where the guide permits it.

Read the site before opening the bag

Keep the counterpoise out of foot traffic and do not place the whip where a fall can reach conductors, vehicles, or people.

Common ways this goes wrong

  • Extending the whip before the base is stable.
  • Leaving the counterpoise on the winder.
  • Using full SS17 length on every higher band when the guide supplies optimized starting lengths.
  • Skipping the tuner check on bands that require it.

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: SS17 and the optional SS25 are documented radiators; another 3/8-24 whip is not automatically equivalent.
Use the current source before deployment.

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