INSTALLATION

A simple station setup using the MFJ-1146 is shown in Figure 4. Place the MFJ-1146 between
your power supply and your radio while keeping the power leads going to the radio as short as
possible. You can attach multiple pieces of equipment to the MFJ-1146, but keep in mind that the
maximum current rating is 40A. Drawing more than that, even if the individual channels are not
near their limits, will burn out the master fuse and require a replacement.
