Hello,

I will be using a single antenna going to an A/B switch so I can feed
the antenna to either one of two Scanners (receive only).

Apparently the switch does Not ground the unused port.

Was wondering if having the scanners antenna input jack just
"floating" while the unit is off has the potential for damaging the
radio ?

I guess I should also ask the corollary: If the unused scanner is
turned On accidentally, and the port is floating as before, any
potential liklihood of damage for this case ?



Like Richard says, most antennas are rather like an "open" circuit,
too, in this regard. If you're concerned about static buildup on those
Receive only antenna inputs, you might consider putting a 1M ohm
resistor across the antenna inputs to chassis ground.
