[Elecraft] KPA500 feature suggestion - band bypass

As Jack points out, the ATU belongs AFTER the KPA500 if you are using 
non-resonant antennas.

if you are using some resonant and some non-resonant, and you want to 
use the KAT3 for the non-resonant, then attach the resonant antennas to 
the KPA500 and the non-resonant antennas to the other antenna connector 
on the KAT3,  This way, the KPA500 will not be subjected to the voltage 
or current extremes that might occur ion the feedline if you attempt to 
put the KPA500 between the ATU and the antenna.

Otherwise, a high-power-capable ATU after the KPA500 will be needed, or 
you will need to bypass the KPA500.
