Bob--

Just as long as you don't equate non-contaminating with
suitable for direct burial.  They are two different things.

Non-contaminating means that the plasticizers in the
jacket won't migrate through the braid and into the
dielectric and degrade performance (increase loss).

Direct burial means that it has a special jacket that
has no pin holes or has a filler type sealant that
eliminates any leakage of water into the cable
and keeps it from migrating through the braid,
thereby increasing losses.
