channel rotary joint. Inspect both coaxes to assure that they are flexible and that the insulation is
not brittle, chaffed or pinched. If any damage is found repair or replace the damaged coaxes. If
damage is due to chaffing, pinching or crushing reroute the new conductors as necessary to prevent
future damage. Assure that all the connectors are properly tightened.

or otherwise damaged.- The metal bars on the top & bottom of the wire-rope isolators should not be
