[amsat-bb] LMR-400 direct to antenna or no?

I hope to put up my first rotating antenna soon and just received a nice length of LMR-400 to use. (regular, not "super-flex")

Having never seen LMR-400 before, I did not know how flexible it would be.  I would call it "medium"... not stiff as a pipe but not floppy, either.

My question is whether anyone using LMR-400 can recommend whether I should attach it directly to my antenna (with slack loops, of course)?

Or, should I get a few meters of something more flexible to attach to an antenna that needs to be free to rotate 360 degrees?

If a jumper is recommended, I would appreciate suggestions on what cable would work best for the task.  The frequency for this project is 70cm.
