Ground Plane Information

  • A ground plane is required with both rod style and shark fin style transponder and FLARM antennas that are not dipole antennas.
  • 1/2 Wave Dipole PN 500101 and the PowerFlarm Dipole do not require ground planes.
  • The smallest recommended ground plane would be the length of antenna inches radius).  So a 4" antenna length ground plane would be 8" optimal.
  • Ground planes can be round or square.  Many discussions on which is best.
  • A ground plane can be  made from a solid plate (such as aluminum flashing) or instead made using 2 wires in a "+" arrangement.
  • Carbon fiber glider fuselages, the antenna mounted on the outside of the fuselage, ground plane on the inside.
  • The mounting screws or bulkhead mounting are connected to the antenna ground.
  • The ground plane can curve and follow the inside of the glider fuselage.

 

The best way to charge the batteries  is to use the PowerFlarm and the Powerflarm 12v DC Power Cable or the PowerFlarm Portable AC Power. The PowerFlarm Portable has to be off to charge the batteries.
