[Elecraft] Array Solutions Lightning Arrestor

[Jim N7US]

Morgan Manufacturing, which, I've heard, was the contract assembly company for ICE, is also selling some of ICE's product line.

In my experience, they fail shorted, so it's pretty obvious.   Although the app notes for both the ICE and Array Solutions products say that they don't always fail shorted.

The design is based on this one, which Array Solutions used to sell, but the ICE owner died several years ago. The circuit is shown in the link below.  The great thing about this circuit is that the inductor continuously discharges static.

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.
