[TowerTalk] Grounding tower guy wires

[donovanf at starpower.net]

Tom,

Each tower has at least one 8 foot ground rod, and the tower foundations are also Ufer grounds.

All guy anchors use eight foot galvanized steel rods directly in contact with the Earth.  I do not have separate ground rods on the anchors.

Feedlines are grounded to the tower base.

I doubt very much that grounding has an effect on the flashovers.  Each guy wire has many insulators, and they all flash over simultaneously.
