As is military practice as well. If you really want to get picky, the
400 should come up to the connector [sealed of course] and supported on
the tower, and then the jumper forms the drip loop to prevent water
running down the coax from running over ... and eventually into ... the
connector.
I don't think I'd run 400 all the way to a rotating antenna.

Would you connect the LMR to the antenna and allow it to move with the
rotation, or run a short length of something much more flexible between the
antenna and LMR?
Commercial practice is to use a flexible jumper and "drip loop" between
the feedline and the antenna, even if the antenna is fixed solid to the
tower/mast. This relieves the stress on the antenna connector.
