What happens when you run the unbalanced antenna into the
unbalanced input?(What a shocking and avante-garde concept!)
Also, there is a simple Navy mod (somebody else can elaborate)
that involves putting a shorting connector into the balanced input
to ground one side and simply swapping the min-bnc cables to
put the other balanced side onto the unbalanced connector. I do
this on all of mine and it works excellent with 75 ohm dipoles and
feedline. I also have a radial array that uses four diploes oriented
in the four cardinal directions and, rather than using a remote
switch, I simply ran a piece of CAT5 network cable and used the
four twisted pairs contained therein. A simply DPQT rotary
switch at the radio end feeds the unbalanced input on my Non-A
directly wih excellent results. These things really like twisted pair
feedline and doublets...an easy field configuration.
