My K3S has Main and Sub receivers. I would like to use Diversity receive
with
the Main using the transmit antenna, and my Sub using a small receive loop.
Is there sufficient isolation on the Receive Only antenna connection to
protect the Sub? Antennas are 60 feet apart, and I intend to run 500 watts
at some point. If I need additional isolation and protection, how would I do
this? Thanks.

>>> Vernon, I would encourage you to give diversity a try. As an early K3
field tester I got my first K3 in 2007 when I lived in a postage stamp sized
lot in CA. I used a variety of RX antennas in full diversity against the TX
antenna, including a Pixel Loop. All those RX antennas were closer to the TX
antenna than what you are proposing. There were many, many times over the
years when having full diversity capability meant the difference between a Q
and no Q. You have very little to lose by giving it a try. 
On caution though... As others have mentioned, I would strongly advise a
front-end protection system.
