Joe,
apples and oranges perhaps?
I think you answered the question as if I was asking about the K3's
input...where as I was asking about the *P3* input which had no gas
discharge protection.
Perhaps I should have mentioned I was speaking of using a standalone P3
for the purpose of chasing rfi, as mentioned in a previous thread:

Don't! Back to back diodes will degrade the strong signal handling
of the K3 and the receive inputs already include protection including
gas discharge and a signal level detector that disconnects the input
if the level becomes too high.

that application?
