[Elecraft] Antenna Question

[Fred Jensen]

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.
