A lot of this stuff is common sense in dressing leads and grounding, both
of which will do more than any other suppression method.
Keep the lines INSIDE the tower when possible, let them exit ONLY at the
tower bottom, bury them when they leave the tower for a good distance, and
install a good radial system ground on the tower. Put a real ground at the
station entrance, and use some common sense and disconnect the lines when a
storm is nearby or when you aren't using the gear.
While the extra gizmo's can't hurt, real damage protection comes from
proper grounding and lead dress and having common sense about disconnecting
power and antenna leads during storms.
