[TowerTalk] Connecting Tower to Ground Rod

[john at kk9a.com]

More ground rods is better, especially if you have a sizable tower.  Look
at the Polyphaser catalog for grounding suggestions.  They sell a ground
strap to tower leg clamp, which is just a hose clamp with a piece of
stainless steel spot welded to it to ensure that the copper strap does not
touch the galvanized tower.

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?


And I'd make that a ground system/network if there is any height to the tower

A single ground rod doesn't provide a lot of protection. I'd consider 1
rod about 3 feet out from each leg a minimum for a 50-60 foot tower with a
tribander on top. Check your code for requirements. They now typically
require two rods at the house entrance. We went to a 200A underground feed
about 10-12 years ago and had to replace the old, single rod with two
about 3 to 5 feet apart IIRC. "I think" there are code requirements for
towers as well
