I have one of these baluns in the workshop. Used to use it to feed a 30M
inverted V, but took it down a few years ago.
The lightning arrestor/suppressor is nothing more than a thin piece of
aluminum strap that connects the eye-bolt at the top of the PVC shell of the
balun (a support rope threads through this eye-bolt) to a ground screw on the
SO-239 at the bottom. Basically a lightning strike will be conducted from the
eye-bolt safely to ground through the coax shield, rather than hitting the
dipole feedpoint just beneath the eye-bolt. Or so the theory goes.
