I'm sure you shouldn't need to worry about blowing out
the front ends of your rigs. The farther your antennas
are apart the better, and make sure that your rigs are
well grounded. You don't need a bunch of rf in the
shack complecating things further. You certainly may
have trouble with cross band interference, If it's not
too bad you can live with it. I haven't done field day
in a few years, but I used to go every year, and I've
had some really good 1's where they hardly interfered
with each other at all, and some really bad 1's where
1 station or the other was virtually unworkable. All I
can say is good luck, but if you have both stations
set up now, you can do some experimenting with
different band combinations to see what's going to
work. Beware of those harmonics. You will certainly
see a big signal on, say 28.480 when the other station
is on 14.240, but if you're lucky It'll drop off
quickly as you move away on 10. You'll probably have
more problems if you're using amplifiers, and if you
go qrp you won't even know the other is keyed down,
*grin*.
