Still, a better topic to read than most of the dreck on here.

I am homebrewing (if that term isn't overkill) a dipole and am using PVC
joints...a T in the middle and straight connectors for the ends. Will
these need to be treated (painted, etc) for UV protection?

Richard, feel free to give this one a pass. :)
You're a good guy, it's just that your prose borders on word salad
sometimes (hold the pedantic dressing)

Even the part about reflections from non-reflective

You are probably thinking of the 8088 (8-bit bus) used
in the low-end version of the first IBM PC. But the
"first IBM computers" were not solid-state. :-) Back
in the 50's, the IBM-650 computers used dual triodes
with a magnetic drum as the memory. The logic was
bi-quinary, somewhat like an abacus.

Cecil:

I am trying to imagine a USRobotics modem the size of my garage!
Probably was the 8088, a '186 would have been a bit of an overkill for
56K and a phone line (but the 8088 probably had head-room left over!)

My experience: White PVC turns brittle under
TX and AZ UV rays.

I have unpainted PVC poles up in Michigan and they have held up for
years with just a bit of powdering of the surface... If you are using
the dipole for a year or three leave it bare... If you think it may be
up for decades, spray with a dark color paint to block UV...
