Typical installations place a mast above the tower, mounted to a rotator 
and in a bearing at the top of the tower.  These connections to the 
tower are through bearings, which puts the bearings at some risk if the 
mast takes a lightning stroke.  Transmission lines from any antennae on 
the mast provide parallel conductive paths to the tower and to the 
ground system.

Is this a problem?

What are some additional ways to ground the mast?  What if the mast and 
tower are both aluminum?
