Beverage Antennas Switch
This switch enables to interface
and switch more beverage antennas using these pre-amps.
It also provides +12V to the middle wire of the coaxial inputs to
source the pre-amplifiers.
It uses TCVR's RX-IN and RX-OUT connectors. Therefore no
high-power switching of the signal path is necessary.
For convenience the OP switches the antennas with a small box
with push buttons. It lies on the desk close to TCVR or to the PC
keyboard. The green button selects the main antenna (the antenna
to which it is transmitted). The gray buttons select one of the
beverage antennas.
