SDC-103 Automatic Screwdriver Controller (ICOM)
Take care and follow your antenna manufacturer's suggestions about routing
these wires for a mobile installation. Avoid routing control wires with the feed
line. Make sure a RF choke is placed around the control lines at the antenna.
The mono data cable should have an RF choke as well.
WARNING: An RF choke must be placed around the control lines at
the antenna. The Controller may be damaged if an RF
choke is not used. MFJ recommends a choke to be
placed on the data cable.
Motor Operating Voltage
This control unit is designed to operate with a screwdriver antenna that operates
on 12 volts. Many antennas operate on only 3 or 4 volts, a Dropping Resistor
can be used inline with the motor wires to bring the voltage down. Consult your
antenna manual or manufacturer for the operating voltage.
Important:
Failure to adjust and operate your screwdriver antenna at
the proper voltage will damage the antenna motor.
If a dropping resistor is necessary, a good value to try is 5 Ω/10 Watts. This
resistor will need to be placed inline on one of the motor control lines anywhere
in between the MFJ-1924 and the antenna. If you are not sure whether or not
this resistor is necessary for your antenna, try it and inspect the torque and speed
of the motor. If the motor is too slow, reduce or eliminate the resistance. Use of
12 volts with a 3 or 4-volt antenna will result in failure of the motor.
WARNING: Do not apply voltages greater than 18 volts to this unit,
or permanent damage to the unit and antenna may result.
