Monopole Antennas 100 Hz - 60 MHz

Our Monopole (both active and passive) 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.
