If the 2nd rx pre-amp can add sufficient gain, then a resistive divider on
that input will add a good degree of protection. Receive-only aerials often
have their own pre-amps, so there might be plenty of gain in hand. Coax to
the 2nd rx should still be protected against common mode current.

Lyle and company,
To be clear are you talking about using another transmitter other
than
the K3's transmitter and external amplifier? This is my reading and I
am
just checking. Thank you.
Both. I believe the OP asked about the sub RX and the K3 transmitter I
broadened the question because I blew out the front end on the K3 while
testing another transmitter. Either situation speaks to how much the K3
receiver can take from external RF. But some solutions such as putting
protective devices in front of the K3 sub receiver will not work of course
when the situation involves the K3 main receiver and an external
transmitter.
