MFJ-4713 Remote Antenna Switch Instruction & Technical Manual
2 SYSTEM SETUP & OPERATION
Seting up the MFJ-4713 is simple. Figure 4 shows one possible station setup that includes the
MFJ-4713. The Control Box is placed on the bench where you can easily reach it. It has a
conveniently folded edge with two screw holes for mounting to the edge of your bench. This both
secures it and keeps it out of the way of the main action. The Switch Box is placed as close to your
antennas as you can get it and has a folded edge with a U-bolt to allow clamping to a mast. The
only connection between the boxes is a single piece of coax. Just make sure to pick coax that can
handle the power you want to run! Finally, plug the AC power adapter into the power port on the
Control Box. Turn the selector switch to the position you want, and you’re ready to operate!
Figure 4: MFJ-4713 Station Setup
Operation of the MFJ-4713 even easier than the setup as there is only a single control. Connect an
antenna to the desired port, then turn the selector switch to match.

If the Switch Box is nearby,
you may hear the relays clicking. This is normal behavior.
