[Elecraft] Protecting the RX ant input K3/K4

Elecrafters :-)

Do some of you protect the RX  ant input to avoid any issue like ''burn'' the RX during transmitt with TX antenna ''close'' to the RX antennas,, I have an Beverage close to my Butternut antenna, but not using my KPA500 at present,so far nothing wrong with the RX,, thinking switch out the ''Beverage'' to GND using relay under TX ? Any better selusion ?
