Times Microwave's LMR-400-UF has a thermoplastic jacket that is porous, and has
a 7-strand copper center conductor.
Times Microwave's LMR-400-DB has a polyethylene jacket that is not porous, is
flooded with a waterproofing compound, and has a 7-strand copper center
conductor.
Davis RF's BuryFlex400 is similar to LMR400DB but, is not flooded, and has a
19-strand copper center conductor.
DX Engineering's DXE400MAX is the same as BuryFlex400. If you factor-in free
ground shipping (on purchases over $100), it's less expensive. Not considering
shipping, a 500' spool from DXE was/is less than the same stuff from Davis RF.
Guess which one I bought when I needed close to 500' for my tower project?

The UF is about the most flexible I've seen, but durable it is not.
BuryFlex is not nearly as flexible, but more than good enough for
rotator loops. It also has a very rugged and slippery jacket.
