Hi Stokely, and thanks for the query.
Most all truly burial cable has a polyethylene jacket, for several
reasons. It is the least permeable to moisture, and very tough and scuff
proof. There is a mistaken idea that MIL SPEC and/or NCV(non
contaminating vinyl) means good for direct burial - indeed some
advertisers and authors encourage this notion. It is not true and never
has been.
Further buriability is available with a moisture-blocking compound
included in the cable's shield area - kind of like a self sealing tire.
It is more expensive, of course, and is valuable in direct immersion,
abusive soils, etc. There is also armored cable available, for extreme
conditions.
In the amateur line, there is good poly covered coax that satisfies the
greatest need, if direct burial is chosen over "in a tube." These include
"Bury-Flex" , 113PE(an RG213 with poly), the LMR line, and hardline.
"Flooded, or "moisture blocked" versions are also available in the LMR
series. In the "8" size, prices range from 45 to about 90 cents per foot.
We can help with any of these, or supply greater detail in a specific
situation if you wish.
Hope this helps
