<What?s the best way to connect the copper wire/strap to the 55G tower leg?

I?m planning to clean the galvanized leg, wrap the leg with a layer of 0.005? 
SS shim stock and then use a couple of SS hose clamps to hold the wire against 
the tower leg.  

Is that the right way to do the attachment?

Should I use any copper paste as well?

##  What does  Rohn have in its catalog ??     They must have the correct 
compression assy for 55-G  legs.  I used 2 gauge stranded copper wire, 
insulated, like RW-90.
One end to cadwelded ground rod, with cadweld and top of ground rod a few 
inched below the ground.    Other end goes to compression lug fitting.   
Correct die used to compress
the lug onto the 2 gauge  stranded cu.  Hole in compression lug  bolted to 
tower base.  But that part  depends on what type of tower it is.   For 
something like  55-G legs, it should
consist of a 2 x piece clamshell  with a big enough flange to handle the mating 
compression lug assy.   Use thin  layer of penetrox goop on the leg, and where 
the mating flange +  
compression fitting bolt together.    SS  +  cu is bad news.  So is  SS  and 
galvanized surfaces.
