MFJ-1924 Screwdriver Controller with Memory Instruction Manual
Introduction
The MFJ-1924 Screwdriver Controller provides manual operation for tuning
screwdriver antennas. In addition, tuned positions can be saved in one of the 10
presets so it can be recalled later. A 4-digit counter is used to display the current
antenna position. A sensor is required for the counter and automatic operation
to function properly. This controller is compatible with single and dual sensor
setups. If your antenna does not have a sensor installed, contact the antenna
manufacturer or MFJ.
