What do you call the small rigid coax similar in size to RG402 but
very rigid. I feel like an idiot after working with this stuff for 20
years and have only refered to it as minature hardline.

Hi Jimmie,

The stuff I use is called MICRO COAX UT (c) 141-SA M17 IUT (r) 141A1

Is UT-141 the same as RG-402? Both solid copper shield?

If it has a solid, usually plain or tinned copper, shield, it's known as
semi-rigid coax. There are no RG numbers associated with it that I know
of -- it's simply specified by impedance and outside diameter - 0.085,
0.141, 0.250 inches and smaller are common. Insulation is usually, but
not always, solid PTFE Teflon. Various manufacturers offer a number of
variations, such as aluminum shield and FEP or foamed dielectric. Each
manufacturer has its own part numbering scheme.

UT-141 is often also labelled RG-402, and UT-085 is often also labelled RG-
405. Some manufacturers seem to think that there is some level of
equivalence.

I added RG-402 and RG-405 to my line loss calculator to cover the
apparently equivalent Uniform Tubes types (ie UT-nnn).

You have lots and lots of company, Jimmie. Don't feel bad.
