As long as there is sufficient isolation in the switch there should be
no problem. I have done exactly as you describe with my KX2 and IC-7100
using a MFJ-1702C switch, which is rated for better than 60 dB of
isolation to 300 MHz.

I'm no expert in this area but I know this list is a wealth of expert
opinion, so here's my question:
I want to buy a two position coaxial switch. I want to connect ONE
antenna to it and switch this antenna between a KX2/KXPA100 (100
watts) and a KX1 (about 3 watts). The coax cable coming from this
switch to the KX2 is a short piece of RG8X and the coax cable going
from this switch to the KX1 is 25' of RG-174 (yes, I already computed
the dB loss and I can live with).
Am I likely to cause any damage to to either piece of equipment?
Thanks,
Stan WB2LQF
