MFJ-1026 Instruction Manual Deluxe Noise Canceling Signal Enhancer
9
WARNING: If an antenna tuner is used, always install the MFJ-1026 between the transceiver
and the tuner. NEVER install the MFJ-1026 between the antenna tuner and
antenna. Never use the MFJ-1026 in conjunction with any internal antenna tuner,
unless the SWR without the tuner is less than 2:1.
When using an amplifier install the MFJ-1026 between the transceiver and the amplifier input. NEVER
install the MFJ-1026 on the output of either an amplifier or antenna tuner!
NEVER
install the MFJ-1026 after an antenna tuner or an amplifier, due to the RF power and voltage
handling limits of the unit. The RF power handling limit of the MFJ-1026 is approximately 100 watts.
Power Supply
This unit requires 10 to 15 volts dc from a negative ground supply. It consumes less than 150 mA
current. The power jack is a 2.1 mm coaxial power receptacle. The outer connection is grounded and the
center pin is the positive terminal.
While we have made every effort to decouple this line for unwanted noise or RF, it is still possible for
unwanted signals to pass from the power or relay control lines to the receiving system. We recommend
testing for unwanted noise ingress by disconnecting all antennas from the unit, and listening to the noise.
You should hear only a smooth low level hiss with the unit turned on and both gain controls at
maximum.
MFJ recommends a 120 Vac to 12 Vdc (nominal voltage) adapter, model number MFJ-1312B, to power
this unit. This power supply has good RF noise immunity.
