| Does this standard apply even if, as in my case, the tower is 190 feet 
from the house entrance?  Does it need to be a direct, dedicated 
connection, or could a hardline shield, for example, be used for the 
tower to house electrical service ground connection.  In cross section, 
even LDF4-50A is a lot beefier than #6.

 National Electrical Code 250.94 will apply to the Rohn Tower and 
grounding. A minimum of #6 copper is required for bonding the tower 
and ground to the electrical service ground. With the galvanized tower 
you don't want a direct copper and galvanizing connection as when wet 
there will be electrolytic corrosion. Stainless Steel, and Aluminum 
are the most commonly used metals which can be used to isolate the 
copper wire from the galvanizing.
NOTE: this BONDING of GROUNDS is the minimum REQUIRED for electrical 
safety. It is NOT adequate for the dissipation of a direct lightning 
strike.

Subject: [TowerTalk] Connecting Tower to Ground Rod
What standardized method can I use to connect the base of a Rohn 25 to a
ground rod driven into the ground very near the base?
