     Most of us here on TT recommend your using solid rather than stranded #2.  
This will eliminate corrosion from between strands, maintaining the electrical 
properties of the grounding wire.

     As for connecting to the tower, you might consider connecting to the flat 
steel elements at the base of the tower using these model 213 clamps from 
Harger: .  I use them to 
connect my shunt-feed wires and my coax shield ground wires to the flat 
elements of my Trylon tower.  I also use their model 222T clamps to connect my ground 
wires to pre-drilled holes in the Trylon's legs.

    A final word of advice:  You ought to connect your ground wires higher up 
along the tower than right atop the concrete base.  This right-angle turn in 
the grounding path represents a greater inductance to lightning energy than a 
gentle curve you get from connecting up higher along the tower legs.  You can 
protect this piece of ground wire with a piece of garden hose that extends a 
few inches into the dirt and above the top of the concrete base.

Subject: [TowerTalk] #2 solid or stranded for tower leg grounds

I acquired 250' of #2 bare copper and 15 ground rods left over from a job at 
work.  So that is a start on what I am using for my ground system for a new 
LM-354HD  crank up tower installation.  Base is installed, waiting for the 
concrete to cure.  Tower is not here yet.
I have to get more wire and rods.  I have most of the exothermic one-shots, but 
of course, need more of them too.  I am pretty much committed to using #2 for 
The plan is to just pigtail up the #2, for now, to each tower leg.
I have a choice of either #2 tinned solid copper or #2 stranded for these 
pigtails.  The one-shots should work with either one by spec. At the moment, I 
am not sure how I will attach the fat #2 to the tower legs.  I was thinking of 
using stranded for that because it would be somewhat more flexible.
Is that a good idea, or should I just stay with the solid?
