Thanks Mike
The wire is going in a machine shop.
Mike I might be a little confused, (please correct me if I am wrong.) When I
say twisted, the cables are definently twisted around each other. The copper
wire inside is not twisted and is solid, is this Cat4? Also the Wire that I
have seen that claims to be shielded is coated in a foil type substance with a
bare wire running on the outside of it. Of course this is all incased in you
typical blue (or color of choice).
The reason we worry about using "shielded" is that that we don't want to be
losing any data do to RF while it is running through the shop.
Conduit would be about the same price to run with labor. As the so called
shielded wire.
Thank you again for you input.

<p> Hello everybody,

am
<br>looking for around 2000ft.
<br> What are the pros to using shielded compared to non shielded?
