$$$$$$$$$$$$$$$$$$$$$$$ that's why home folks can't
do the same thing (at UHF). Look at the price of filters
that separate next adjacent channels. The limiting factor
for adjacent channels can in some cases (like mine) be the
quality of filters in the transmitters.
The correct solution is accessory outputs of tuners that
send signals to external preamps to turn on and off, or
an external switcher, the latter being quite cheap. Then you can
do a scan for each antenna and select out duplicates.
