Thanks for the response. We just last night had another thunderstorm,
depositing plenty of noise and lightning nearby. Our house is physically
lower than the houses on either side, and the end of our yard has a very
tall Silver Maple tree, to which my random wire antenna runs from the
house. The wire ends about 7 feet from the tree trunk, and is tied to the
tree with the rubber strip that is used to hold screens in windows frames.
I fear that a strike to the tree will impart more than static to the random
wire antenna.

Perhaps you, RHF, Jack Painter, or others can comment on how to protect the
random wire from transferring a lightning strike to the tree from following
the antenna wire. As I sleep by the radio, I don't with to be awakened
writhing from a lightning strike.

The higher the ends above ground, the better.
You have less earth loss. There is no need to
use lightning arresters at the tips of the dipoles
to ground. If the wire were actually close enough
to ground to arc to ground, it will do it, arrester, or
not.................
