Yes. We've pumped several watts into the KRX3's aux antenna input 
without any sign of damage. (But anything above about 1 to 2 watts 
measured at the sub's AUX input will activate the carrier-operated 
relay, or COR, which should be avoided because it slows down break-in 
keying receive recovery.)

As long as the receive antenna is a reasonable distance from the 
transmit antenna, the COR won't be activated, and you'll be at a safe 
level. The AUX BNC jack provides somewhat better isolation than the 
KAT3 connector, so it may be the better choice if you're not sure if 
the antennas are far enough apart at the intended power level.
