Your going to get a lot of answers on this one, but...

I have always run a ground rod for the radio gear as close to the 
operating point as possible.  In my present station,  I drilled a 3/4" 
hole through the foundation and drove a ground rod in under my desk.  My 
radio and Amp tie to this ground.   At the point of feedline entry about 
80' away I have another ground rod just below an aluminum plate with 
bulkhead N's and SO239's.  The feed though ground has a #4 solid copper 
wire buried to tie in to the tower ground's, but I am not able to tie it 
back to the radio ground rod at this QTH (I have done so at former QTH's).

Sometimes the best you can do has to be good enough.
