No & no. There should be a ground rod out from the foundation in line 
with each leg.  The distance isn't critical but an 8 to 10' ground rod 
would typically be about 4' to 5' out. These should be tied to the the 
ground rods for the house electrical ground as well. As Gary said, the 
ground wire run from the antenna to the base of the tower is not really 
of any use.
