I used BURY-FLEX(TM) <http://www.davisrf.com/ham1/coax.htm#buryflex>, which
I believe was developed especially for such antennas.

"Commercial entities are pleased with its tough, high durometer, outer
jacket and many hams can lay this cable in grass and woods without worry of
abrasion or animal gnawing."
