[TowerTalk] Beverage termination - Surge Arrestor selection?

[George Dubovsky]

I would think the gas tube would be ok, low shunt C and all that, but the
MOV would likely be bad. I use dual-element gas tubes across the line on
both ends of my bi-directional Beverages, and although I have never done a
before/after test, I do seem to have "normal" Beverage directivity.
