Product Details
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.

This adjustable antenna mount has a rugged 4" mounting surface with a Captive 1/4-20 male thread for mounting all of A.H. Systems and most other compliance measurement antennas.
SAC-212 - 3 Meter BNC/N Cable
Our custom made microwave/RF cable assemblies provide repeatable, reliable performance for use in a variety of commercial and industrial applications.
ECF-10 - ECSM Fixture
The ECF-10 is a 10 pF capacitance fixture used for system checks and calibration of the active monopole antennas. One of the functions of the matching network is to convert the high impedance input of the antenna element to the 50 ohm impedance of the measurement receiver. The 10 pF capacitor ensures that the correct source impedance is present during the check.
