Lightening arresters don't have to handle that much energy.
When a strike hits a mast with an antenna on it the current divides. Most
of it should go straight down the tower or mast into the ground. This is
why the structure is bonded to a grounding system using a straight line
path with ground
Hi
Any form of protection (no matter what you are protecting against) is part of a
system. The more complex the system, the more it costs and the larger it gets.
The more details you cover in your system the more 9’s you get to put in the

Two of nature's great forces are hurricanes and thunderstorms.
A cloud with dimensions measured in miles can accumulate a great deal of
static charge during a storm, thousands of times more than any
human-built accumulator. When the volts/meter between the cloud and the
ground become high enough,
Bark effect? ;-)
Lightning hit a tree behind where I lived and three other trees near it also
exploded... you ain't gonna arrest a direct lightning strike.

Skin effect did not save the tree.
