I also do not do this. I assumed that the mast is grounded though the
thrust bearing and the rotator bearing. Of course multi-multi stations
like W3LPL can have rectification issues that do most of us do not have.
>From a lightning standpoint I have had no problems with the mast simply
bolted to the bearing and rotator.

> W3LPL has alerted us to the fact that passive intermod is often
generated within rotor housings, the solution for which is to bond
around the rotor. What do you recommend for making the connection to the
mast above the rotor?
I dunno. What does the new N0AX grounding book say? My answer would
probably be to use some sort of stranded insulated wire with a hose clamp on
the mast and the bottom end connected to the tower - connection type your
choice with some anti-oxidant on each end.
To be honest I've never done this.
