A.H. Systems Model Active Monopole Antennas

CHARGING THE BATTERY

Depending on the model (if applicable) position the input voltage selector

located next to the wall plug on the back of charger to the proper voltage (either

110-120 VAC 60 Hz or 220-240 VAC 50 Hz). Be sure to check available voltage

and adjust selector as needed before use. The amplifier ON-OFF switch must

be in the OFF/CHARGE position to charge the battery. One hour of amplifier

operation will be obtained for each hour of charge up to a maximum of 8 hours

operation. Charging for up to 24 hours will not damage the battery. Using the

battery charger to operate the amplifier directly is not recommended.

ECF-10 (Equivalent Capacitance Fixture)

The ECF-10 is an equivalent capacitance fixture constructed per IEEE 291 and

ARP 958. This is an indispensable tool used for gain adjustment and calibration

of the active monopoles. The ECF-10 is used as a signal substitution source

when calibrating the active monopole. Refer to the alignment and calibration

procedures below.
