No one recommends using 9913 or any solid centered coax where it has to
move occasionally; i.e. rotation loop. Besides the center conductor moving
around inside the air dielectric, the solid center conductor will work
eventually
work harden and crack - bad news for any feedline. Terminate the 9913 at the
top of the tower and use any old stranded center conductor coax to the beam.
