MFJ-4724 Desktop/Remote Antenna/Transceiver Switch 

Instruction Manual

 

INSTALLATION

 

 

1.  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.  

 

2.  Connect your antennas to the SO-239 coax connectors numbered 1-4. 

Note which antenna is connected to each connector. 

 

3.  Connect your transceivers to the SO-239 coax connectors labeled A-D.  

Note which transceiver is connected to each connector. 

 

4.  Connect a feedline from the TRANSMITTER COMMON connector to the 

ANTENNA COMMON connector. 

 

5.  Connect the station ground to the GROUND connector. 

 

6.  If your Transceiver is equipped with a 12VDC accessory jack, you may 

connect it to the Antenna/Transceiver Switch using a RCA plug so when 
your Transceiver is off, all inputs are automatically grounded.  
You may also connect the Antenna/Transceiver Switch to your power 
supply using a RCA plug, so when you turn off the power supply, all inputs 
are automatically grounded. 

 

7.  If you are using the MFJ-4724RC Remote Control, connect the RJ-45 

modular jack from the ANTENNA jack on the Remote Control to the 
ANTENNA REMOTE jack on the back of the unit and connect the RJ-45 
modular jack from the TRANSCIEVER jack on the Remote Control to the 
TRANSCIEVER REMOTE jack on the back of the unit using a CAT-5 
cable. 

 

8.   If your Transceiver is equipped with a 12VDC accessory jack, you may 

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

 

9.  An additional remote mount option is to remove the cover, remove the 

knob-shaft coupler using an Allen wrench and remove the knob.  Now, the 
unit can be placed facedown if desired.
