Good stuff, Terry.
Twisted pair or coax are just engineering solutions to a problem. Both
have their place depending on what you want to accomplish, money spent,
et cetera.

I wasn't trying say that coax is always "better" then twisted, but
after the 150
nonesense posts on the subject I wanted to dump some reality based math
on the subject.
As I have pointed out before in this NG, even coax can suffer from
ingress.
It just has a lot less then any balanced line I have experimented with.
I use balanced audio, video, data and networking, lines everyday at
work and
at home. But for low level RF distribution I have found that coax,
triax or twinax
beats any sort of balanced line when it comes to keeping iterference
out.
I still wish the proponenets on both sides would just string ~100' of
each type
line out, terminate properly, couple to the receiver properly, ie use a
transformer
to convert the balanced to unbalanced, and see which has the most
"stary" signal
pickup.
I want to do every thing I can to make sure that my 1uV signal from my
antenna
doesn't get smoothered in crud before it gets into my receiver. I get
enough crud
from the electronic crap that surrounds me.
