The Top Ten Devices unit plugs into the band data jack of the radio and,
in my application, replaces the DX Engineering remote antenna switch
controller. When I change bands on the radio the remote switch on the
top of my tower switches to the appropriate antenna for that bands, so I
don't have to do it manually.
The Top Ten box has its own power supply for the remote switch and can
be easily configured for monoband antennas or monoband antennas and a
tribander.

Hello,
I'm trying to follow this discussion and have a question. What is a Top
Ten
Devices Band Decoder? Sorry, for my ignorance. Thank you for the
information.
Best,
