Hi
You are going to fabricate the “base” as a solid piece. Getting a coax style connector
into that is just a matter of your credit limit. The larger issue on the device is making the
“cover” out of metal. That probably isn’t going to work very well :) Now you are off into
a glass cover of some sort with a weld flange on it. If you thought the tooling on the
coax connector was exciting, it just took second place …
==========
The bigger question is: If you had the choice of a > $5,000 version of this device that
would not fail from (internal) humidity, would you buy a few thousand of them? My guess
is that you would still buy the $250 ( I *think* that was the original price …) version and
a couple of spares.
I’d bet more of them die from lightning hits than from humidity.
