Ian,
That all depends.
There is no one answer, because it depends on how much energy from the
other transmitters is going to be picked up by your RX antenna.
If it enough to operate the COR (you will hear the relay clicking), then
you should provide some protection.
Providing that protection without actually setting up the proposed Field
Day antennas and transmitters and experimenting is the 'safe' way to do it.
If you prefer not to do that, I would suggest you do set up a "practice
Field Day" with the antennas and transmitters as they will be for the
actual Field Day and try it out using all combinations of bands,
transmitters and antennas that you plan to use.
There may be simulation programs that will tell you how much RF energy
is coupled from one antenna to another, but I don't know what those
programs might be.

I don't anticipate using a RX antenna any time soon on my K3S but I will use
it at Field Day with 5-4 other 100W transmitters. Any reason to use a
DXE-RG-5000 front-end protection device across the RX-IN and RX-out ports?
Or is there sufficient internal protection?
