MFJ -1024 Quick Start Manual

The MFJ-1024 Remote Active Antenna is designed to provide reception of
radio signals from 50 KHz to 30 MHz using a remote mounted antenna and
amplifier module.
1. Attach the remote unit to your pole or other mounting location and
run the cable to your receiver location.
2. Connect the cable from the remote unit to the REMOTE ANTENNA jack
on the back of the base unit. The jack is a PL-259 type.
3. Connect a 12-15 VDC power supply or an MFJ 12V AC adapter
to the PWR jack on the back of the base unit. The power jack
accepts a 2.5mm subminiature plug, with the tip positive.
4. Connect your receiver or receivers to the jacks labeled
RECEIVER A and RECEIVER B on the back of the base unit. The
jacks accept RCA type plugs.
5. If desired, an auxilliary antenna may be connected to the AUX
ANT jack on the base unit.
After proper installation of the Remote Active Antenna, turn on your
receiver and depress the PWR ON switch on the antenna base unit. The
front panel LED should light, indicating circuit operation. Select
receiver A or B by pressing the REC A/B switch. Set the attenuation
switch to -Odb. Set the GAIN control to the 9 o'clock position.
Tune your receiver to the frequency you wish to listen to.
Increase GAIN to desired level. Best circuit operation may be
achieved at less than maximum GAIN setting. On very strong signals
that may overload your receiver, it may be necessary to set the
attenuation switch to the -20db position to reduce the signal
strength.
NOTE: On some portable receivers, especially those with plastic
cabinets, oscillation may occur at some frequencies if GAIN is set
too high. If this happens, reduce the level of the GAIN control until
oscillations disappear.
When the power switch is in the AUX position the power to the remote
antenna and amplifier module is cut off and your receiver is connected
to the auxilliary antenna jack on the base unit. Any antenna of your
choise may be connected to the jack. When the unit is in the
auxilliary mode, the GAIN control is not operational, but the
attenuation and receiver select controls will work with your auxilliary
antenna.
