A.H. Systems SAS-550-2 Active Directional Antenna; 100 Hz to 60 MHz
The A.H. Systems Active Monopole Antenna is an active, general-purpose, receive-only antenna that covers 100 Hz - 60 MHz frequency range. 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. This antenna is an ideal solution to perform FCC, MIL-STD and TEMPEST tests.
