Monopole Antennas 100 Hz - 60 MHz

Our Monopole Antennas provide superior performance in electric field measurements. The Active Monopole Antenna can drive any receiver with 50 ohm input impedance and will perform FCC, MIL-STD and TEMPEST tests. The passive rod is used for transmitting, to perform shielding effectiveness and immunity testing. Click on a model below to learn more about it's characteristics.
