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

 
INSTALLATION

 

 

1.  See the MFJ-4726 Instruction manual for complete 

instructions. 

 

2.  The unit can be located at any convenient location, as 

long as it is not exposed to moisture. It should be 
grounded to the station ground, and preferably 
powered from a separate wall adaptor.  

 
3.  Connect your antennas to the SO-239 coax 

connectors numbered 1-6. Note which antenna is 
connected to each connector. 

 

4.  Connect your transceivers to the SO-239 coax 

connectors labeled A-F.  Note which transceiver is 
connected to each connector. 

 
5.  Connect a feedline from the TRANSMITTER 

COMMON connector to the ANTENNA COMMON 
connector. 

 
6.  Connect the station ground to the GROUND 

connector. 

 

7.  When using the MFJ-4726RC Remote Control, 

connect a RJ-45 modular jack from the remote control 
to the ANTENNA REMOTE jack on the back of the 
unit and connect a RJ-45 modular jack from the 
remote control to the TRANSMITTER REMOTE jack 
on the back of the unit using a CAT-5 cable.   

 
6.  If your Transceiver is equipped with a Radio Sense 

jack, you may connect it to the Remote Control using 
a RCA plug so when your Transceiver is off, all inputs 
are automatically grounded.
