Glenn is one of the experts in antenna/tower installations.  Look up
"asperities" or "asperity" for the microscopic roughness of metals.  Dan

If you looked at the aluminum surface with a microscope, after prep, 
you would of course see a rough landscape of bumps and grooves-- not 
smooth.  When the two surfaces are mashed together tightly with a 
hose clamp, and a screw added, don't worry-- plenty of the high spots 
are going to mate up with other high spots, regardless of the 
presence of the dielectric, and make contact.  That is the series of 
multiple contact points from which we are trying to eliminate the oxygen.
