Pete, I take hits directly on my towers all the time, and I never disconnect the K3 or any other rig. Of course my closest tower is about 150 feet away, so this might not work if you get a hit just feet away where the EMP is huge, but a good system will significantly reduce chances of a problem. With the spacing I have from towers to house the problems are virtually gone, this includes the contest barn that is only about 75-100 feet from the one 200 foot tower.
