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

. Each unit comes with a telescoping rod, ground plane with a high impedance

matched preamplifier and battery charger. Review this manual and become

familiar with all safety markings and instructions. Verify that the antenna

impedance is compatible with the receiver impedance.
