MFJ MFJ-1022 User Manual

INTRODUCTION

The MFJ-1022 ACTIVE ANTENNA is designed to provide receptio n of
radio signals when an outside antenna is not possible. It
covers all international shortwave bands and amateur high
frequency bands. Portability is made possible by the
internal telescoping antenna and operation from a 9V
transistor battery.

INSTALLATION

1. Attach the telescoping antenna to the MFJ-1022 by screwing
it o n t o t h e board through the hole provided in the top of
the cabinet.

2. The MFJ-1022 requires the optional MFJ-1312B power supply
adapter or a nine-volt transistor battery. A power supply
may be used by connecting a 2.1 mm plug to the cable with
the tip positive.

3. Connect a coax cable from the SO-239 on the MFJ-1022 to
the antenna input on the receiver.

4. If using the internal telescoping antenna, be sure it is
fully extended prior to use.

NOTE: Fluorescent lamps, electric motors, microwave
ovens, TV sets, and other electrical or electronic devices
can generate noise which may be picked up by the MFJ-1022.
If this occurs, it may be necessary to turn the device
generating the noise off while the MFJ-1022 is in use.

OPERATION

After proper connection of the MFJ-1022, depress the power
switch. When the power switch is depressed, power is
applied to the circuit, the LED on the front panel lights
indicating power on.
