Has anyone here had any personal experience with the MFJ Remote Switch,
MFJ-4712? If so, how well does it work, and how is the 12 volts fed to the
remote switch using the coax to carry the necessary voltage to the remote
switch? That is how do they separate the RF and the DC? I know how I would
do it if I were designing the switch, but I would like to know how MFJ does
it.
