Until K9YC's post I was not aware of the Array Solutions lightning
arrestor. They appear be a nice product. How do GDT's fail - open or
closed? If open, how do you know that they need replacement?

I strongly agree with Bob's advice, EXCEPT that I've gotten really tired
of replacing Polyphasers on my high wire dipoles. I've recently switched
to the arrestors that Array Solutions sells, both because I like the
circuit better and because the gas discharge tubes are user replaceable.
The Polyphasers are feed-through types mounted to the entry panel. The
Array Solutions are mounted in a big Hoffman box, for which W6GJB built
some custom mounting brackets. It's mounted to the wall next to the
plate with the Polyphasers, with two 2-in PVC conduit stubs going
through the wall and holes drilled at the bottom of the enclosure for
coax entry.
