NGP (No Ground Plane)

If you try to use standard ground-based CB equipment with a vehicle that needs a "no ground plane" antenna, you'll experience both high SWR levels and extremely poor performance. Vehicles that require NGP equipment:

  • Have a fiberglass shell or coating over much or all of the vehicle
  • Have little or no metallic chassis for the antenna to be grounded to

Vehicals that should use NGP products:

  • Motor homes and large fiberglass coaches
  • Camper shells where the antenna is mounted directly to the fiberglass (instead of the vehicle)
  • Boats
  • Motorcycles with little or no ground plane
