I do use these ICE coax grounding blocks. They're 
machined to close tolerances and they supply ample goop 
made of special particles for joining AL and Cu 
materials.  They're mounted across two of the tower legs 
down at the base of the tower.  Since they're connected 
to the tower they therefore are also connected to the 
tower ground system; I ran no other jumper from them to 
the ground system.  They seem to seal against moisture 
ingress but I'm real anal and I sealed the edges with 
coax seal also.  I've had occasion to open one up after 
six months of winter and weather and the shield looked 
bright and shiny.  Pretty easy to install; you need to 
specify your tower type (they'll build custom made if 
needed) and your coax type.  Phil  KB9CRY
