MFJ-1924 Screwdriver Controller with Memory 

Instruction Manual 

   

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.
