EMC and Transmitter Interference

Shielding & Earthing

  • Equipment should be adequately shielded, generally in an earthed metal enclosure
  • This prevents radiation leaving or entering the device
  • A separate RF earth will prevent signals flowing on the mains (safety) earth; it will also reduce noise pick-up by the amateur station
  • This separate earth should consist of several earth rods, connected by thick wire or braid
