A.H. Systems Model Active Monopole Antennas SPECIFICATIONS GENERAL DESCRIPTION The A.H. Systems active monopole antennas are active, general-purpose, receive-only antennas which cover the 100 Hz – 60 MHz frequency range. They are ideal for instantaneous bandwidth scanning (without tuning) of electric fields in its frequency range and can drive any receiver with an input impedance of 50 . -

The signal field strength is the receiver voltage in dBV plus the antenna factor (refer to the antenna factor calibration tables) plus any cable loss. A.H. Systems inc. – Nov 2019 REV D... - Page 7 ARP 958. This is an indispensable tool used for gain adjustment and calibration of the active monopole antennas. The ECF-10K is used as a signal substitution source when calibrating the active monopole antennas. Refer to the alignment and calibration procedures below. A.H. Systems inc. – Nov 2019 REV D...
