Active Monopole Antenna

  • The 41 inch Monopole antenna is required for making electric field emission measurements below 60 MHz per Military standards (MIL-STD-461) and FAA (DO-160) specifications.
  • This antenna is for emissions measurements only. It cannot be used for transmitting.
  • The Active Monopole antenna is generally used in a shielded room or in a screen room, with the equipment under test (EUT) placed on a metal ground plane.
  • The 41 inch rod and the ground plane behave electrically as though a mirror image of the rod were located below the ground, and the ground removed. Since the stainless steel plate does not have enough surface area to mirror the entire 41 inch rod, it is bonded to the surrounding ground plane during use.
  • The AM-741 is battery powered to prevent measurement errors that maybe caused by external power cables. The ANSI equivalent capacitance substitution method (ECSM) is recommended method for calibrating AM-741R monopole antenna. The individual calibration data will be included with each antenna.
