Not sure what you call this box, but it is supposed to extend the range of
built-in antenna tuners. I bought one of these used a while back, but
don't have a clue how to use it. It has 3 s o 239 connecters, what are
these? Also, I assume the switch on top selects more capacitance or
something. Any help appreciated.
