Yes and no. In my case the insulators breaking up the wires are more to
allow shunt feeding the tower for low bands. But lightning will most
likely ignore a few paltry 2 or 3 inch gaps at the insulators and go
down the wires anyway. You can't ground the middle sections of wire, but
it is my understanding you should still ground the last section near
the anchor.
