NEC requires minimum 6 ft. between ground electrodes..for better  
performance minimum 2X electrode length (e.g. 16 ft for 8 ft rods).

Excellent point Jim.  All services' grounds (AC, telephone,  television, 
internet and ham shack cable entry point & ham tower) must be  bonded to a 
single-point ground system.  There's no limit on number of  ground rods as long 
as they're bonded (i.e. tied to the same grounding  system).  8 foot ground 
rods need to be within 16 ft of each other, but  can be closer if needed to 
shorten cable run to each service ground  connection.

Couple more good references for grounding and bonding  standards from 
Motorola &  Harris:
