EHA-51B - Battery Operated Active Monopole And 12" Loop Antenna

A.H. Systems EHA-51B Antenna is an active, general-purpose, receive-only monopole and loop antenna for magnetic and electric field testing.


  • Broad Frequency Range of 1 KHz to 60 MHz
  • Individually Calibrated
  • FCC, MIL-STD, VDE and TEMPEST Testing
  • Rugged Construction
  • Battery Operated for Enhanced Portability

Included Equipment

  • Switchable Preamplifier/matching network
  • 12" shielded Loop antenna
  • Telescoping Rod Antenna
  • Battery Charger
  • ADP-201 BNC(f) to N(m) Adapter

As a monopole antenna it is ideal for instantaneous bandwidth scanning (without tuning) of electric fields in its frequency range and can drive any receiver with 50-ohm input impedance.

The EHA-51B is also an active receive only loop antenna for magnetic field testing. This loop antenna is ideal for emissions testing and has a balanced Faraday shield to reduce the E-field response for a pure magnetic field measurement. It is suitable for MIL-STD, VDE, and TEMPEST testing, with reliable, repeatable measurements.
