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.
