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).
Typically PVC IIA

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.

The worst thing that manufacturers and dealers say
is RG-8 TYPE or RG-213 TYPE.    TYPE means
"sorta like--but not really"   Stay away from anything
that is called "something--type".
