Electrically speaking the answer is zero. The most important thing
about power and communications grounding electrodes that serve the
same structure is that they should be bonded together to form a single
grounding electrode system. If the two grounding electrodes are not
combined into a single system then differences between them will
equalize destructively through expensive electronic equipment and
appliances. Best practice is to build one grounding electrode system
and use it for all of the wire carried utilities that enter your home.
