  • Ae30-300 - H-field active loop antenna The principle of operation is that an RF voltage appears across the terminals of a loop when it is placed in an electromagnetic field. This voltage is proportional to frequency for a given field strength. Therefore at Very Low Frequencies, the voltage is very small, and requires greater amplification.

  • 7429-1 - Loop Antenna The loop antenna used for generating radiated magnetic fields is fully described in Figure 1A of MIL-STD-461A. It consists of ten turns of number 16 AWG wire on an insulated form 4.72" (12 cm) in diameter. The winding is placed on the form in a position which allows the form to be used as a spacer to place the winding 5 cm from the face of the item under test as required by Test Method RS01 of MIL-STD-462.

  • HM525 - Active H-Field Measurement Antenna The Active H-Field Measurement Antenna HM525 is a loop antenna. The voltage at its output is proportional to the amplitude of the alternating magnetic field applied. For overview measurements, the antenna can be operated in broadband mode in the total frequency range from 100 Hz to 30 MHz. To obtain maximum sensitivity, the antenna can be locally or remotely switched to the subrange mode. In this case the frequency range is divided into five subranges with different amplifier concepts in the active antenna part. For a functional check the antenna can be operated in the test mode. The antenna is individually calibrated by comparison and comes with a calibration report.
