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.

In my opinion, the best lightning arrestor products for up to 1.5 kw
transmission systems are made by Industrial Communication Engineers (ICE).
Solutions for either open-wire (no coax feed involved) or coaxial feedline
arrestors are shown at Array Solutions, the distributor for I.C.E.

ICE also makes very convenient grounding blocks for the custom connections
of coax shield grounding. This allows a "manifold" connection of several
coax shield grounds to a ground rod and works very well. But Andrews and
Harger and others also make those, and Harger is probably the best for
grounding materials in general. Local electrical distributors will carry (or
order) Harger products.
