MFJ-4726RC 6–Position Antenna/Transceiver Switch Remote Control 

 
OPERATION 

 
 

1.  Connect the 2.1mm plug DC power supply to the 

Remote Control.  The supply must be capable of 
supplying 300mA continuous at 12-15 volts DC. This 
unit is polarity sensitive.  It requires the following 
power connection: 

 

 

 
The sleeve is negative, and can be grounded or 
floated at the power supply.  The center pin is 
positive, and MUST be ground isolated. 

 
 

2.  Rotate the Selector Knob on the MFJ-4726 

Desktop/Remote Antenna/Transceiver Switch to the 
OFF/Remote position.   

 

3. 

Rotate the Selector Knobs on the Remote Control to 
choose the desired antenna and transceiver.  The 
switch positions are numbered and lettered on the 
front of the control panel and a space is provided to 
pencil in the designation for each antenna and 
transceiver.  

 

 

IMPORTANT:

  

NEVER switch antennas with RF power applied to the  

Master feedline.  Damage to the switching contacts may result  from 
“hot-switching”.
