Go to the site, navigate to the picture tour, "To take a tour of the main repeater site click here!" to view a rather comprehensive repeater setup using Polyphasors exclusively. http://220.127.116.11/gpvhfs/
I spearheaded that design after the gpvhfs repeater system suffered too many instances of lightning damage during storm season.
Direct hits, the thing still works.
Polyphasor has changed hands to a large corporate endeavor now, and they have stopped offering the original guarantee that "Dr. Lightning" had when he owned the company that was a direct result of his lightning research -- for the commercial broadcasters, using his recommended protectors and procedures, his written guarantee was to replace ANY equipment damaged by lightning strike. To my knowledge, he never had to honor that warranty. Which would have proved very expensive considering the cost of some of those 100KW FM or TV transmitters.
When installed correctly, Polyphasor works.
Of course, there can always be that catastrophic event when dealing with mother nature...
