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?
