HELLO ALL:

GREAT TOPIC….GROUNDING & BONDING.

If you haven’t seen Tom Rauch’s discourse on Grounding systems, it’s worth a critical reading.  See:  https://www.w8ji.com/ground_systems.htm.

Tom is the senior engineer and consultant with DX Engineering.  You can get a graduate degree in ham radio and RF engineering reading Tom’s website.

73,
Dave. N1RF

Also, what voltages/currents would cause lasting damage to a healthy tree? What would the connection to the tree be? (Drill a hole, insert a copper or aluminum pipe? Idk)
