A.H. Systems Model Active Monopole Antennas

OPERATING INSTRUCTIONS

ASSEMBLY INSTRUCTIONS

To prepare the antenna for operation, attach the telescoping rod antenna

element to the top of the high impedance preamplifier. Connect the rod antenna

by pushing straight down on the female connector on top of the amplifier. Do

not apply excessive sideways force, as this can cause the antenna center-pin to

break. Do not operate the Monopole antenna with the Battery charger

connected.

SETUP INSTRUCTIONS

The amplifier and ground plane can be mounted to any tripod with a 1/4-20

attaching stud. Attach the rod antenna to the connector on the top of the

amplifier. Extend the rod antenna to 41" (104cm) above the ground plane.

Connect the output BNC connector on the side of the amplifier to the input of a

50-ohm receiver or spectrum analyzer. Make ground connection to ground

plane if required by the test specification.

The POWER indicator LED will light and stay lit as long as the battery has

sufficient voltage to power the preamplifier. If the LED does not light, do not use

the preamplifier until the battery has been recharged.

GENERAL USE INSTRUCTIONS

The calibration tables provide a listing of the frequency of operation and it's

antenna factor in dB/m. The field strength is the receiver voltage in dBuV plus

the antenna factor (refer to the antenna factor calibration) plus any cable loss.

When making a measurement, mount the antenna on an appropriate mast or

tripod. Ensure that the Monopole is turned on and use the appropriate The

Active Monopole Antenna is easy to set up and provides good reception with a

minimal need for space. It's flat 0dB Antenna Factor makes it a convent choice

when calculating the field intensity. The signal field strength is the receiver

voltage in dBuV plus the antenna factor (refer to the antenna factor calibration)

plus any cable loss.

NOTE: The on/off toggle switch is a locking type to prevent

accidental turn-on or turn-off. Pull out on the toggle handle

and push up to turn amplifier power on. Pull out and push

down to turn off.
