[Milsurplus] What is this thing??

I've spent some time with those things.
It is the Antenna Switch for a pair
of BC-446 LF Loop Radio Range Transmitters.
The antenna was made up of two loops placed
90 degrees to each other. (Breck, you can
explain all this.)  The picture with two sets
of four insulators is the transmitter side.
The other side is the antenna side, and the
switch knobs are on the ends.  You wouldn't
want that thing to be made of metal.
