"I saw to what extent the people among whom I lived could be trusted as good neighbors and friends; that their friendship was for summer weather only; that they did not greatly propose to do right; that they were a distinct race from me by their prejudices and superstitions."
Henry David Thoreau

The wrench does seem a trifle oversize for the brass compression fittings.
It fits the big nut on the regulator fitting very well, though.
Exactly what are we looking at?
A set of dry nitrogen cylinders, a gas distribution manifold for dry nitrogen/dry air (there's a compresser/dehydrator just out of the frame) and a set of three pressure switches, one of which is no longer connected.
This whole mess keeps large coaxial RF transmision line filled with dry gas, to prevent it collecting condensation, corroding and burning up. One of the lines tripped a pressure alarm yesterday morning and I had to go see what was the matter. Turned out to be a combination of minor, unfortunate events, none of them critical in and of themselves.
Does the RF tuning change when you go from dry air to pure N2?
I have vague memories of my EE theory class where we analyzed waveguides.
Always fun to see the bits and bobs behind the high tech stuff at your office.
Well, it almost works as a Golden Age movie set, doesn't it?
Cool! Worked around that type of feed line a time or two across the years but never saw the actual gas feeding system.
Huh, The things I don't know about radio engineering will apparently fill a library. Glad somebody is on top of this.
really all that for RF transmission? why I do feel like one of the lines leads to keg of good Irish stout?
