PVC jackets on cable outdoors, especially buried, is risky. I use alot of 
it myself outside, including cat 3 and cat 5 200ft to the weather station 
on the tower. Not a great practice.   A PVC jacket, when frozen, may 
crack,  And the pvc will not hold up anywhere as well as a polyethylene 
(PE). For inside fixed cabling  it's perfect.  Most good mike cables are 
rubber, not a stiff pvc .  For you northerners, notice how the coil cord on 
your mobile mike acts in winter, till your car warms.

>I notice that Digi-Key is selling CAT-3 network cable for $72/1000ft.  It
>has 8 #24 conductors, which suggests that at least for my run (~200 ft.),
>it can be used with TopTen relay boxes with minimal voltage drop (about
>2/10 of a volt at 20 ma).  anyone had any experience with this outside?
>The outside is grey pvc, and each conductor is fully insulated, also with PVC.

>Anyone had relevant experience?  The price is sure right.
