Hello John,
LMR-400DB is direct burial hence DB (Direct Burial).
In the LMR category you have besides the "standard" cable the
following options.
FR - fire retardant for installation in vertical building raisers
LLPL - low loss plenum cable for use in any in building aps including
air handling plenums and spaces where maximum fire retarandcy and
minimum smoke generation are required.
DB - water tight cables with an inert flooding for direct burial
UF - ultraflex stranded center conductor cables with flexble outer
jacket
All of this is covered in Times Microwaves discovery document.
