Stan,

If your maximum power is 100 watts and the isolation of the switch is 40dB or more then I don't think you have any problem.

I would like to use a coaxial switch for an unintended use and I'm not

equipment damage.

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
