A.H. Systems EHA-51B Antenna is an active, general-purpose, receive-only monopole and loop antenna for magnetic and electric field testing.
The A.H. Systems EHA-51B Antenna is an active, general-purpose, receive-only antenna that covers 1 KHz - 60 MHz. This antenna has a switchable front end for receiving as a monopole or loop antenna.
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.
