I am getting ready to purchase a Jetstream JTLA2 Lighting Arrestor for my 2m/440 station. There is a ground screw on each side of the little unit. Should I ground both screws or what is it used for?
You only have to ground one, they provide two for multiple situations, but both screws are in the same aluminum extrusion that makes up the body, so only grounding one is necessary.
