    MEDIUM-DUTY ANTENNA ELEVATION ROTATOR & CONTROLLER The Yaesu G-550 provides 180° elevation control of unidirectional satellite antenna arrays under remote control from the station operating position. The factory-lubri- cated rotator unit is housed in weatherproof melamine resin coated die-cast alumi- num, to provide maintenance-free operation under all climatic conditions.

The diagrams below show several recommended installations. Notice that the pre- ferred mounting method requires that each antenna be attached to the boom at its center of gravity, with the boom there attached to the rotator at its center of gravity.
  • Page 8 G-550 I Be sure to leave enough slack in both the elevation control cable and the coaxial cable feedline around the azimuth rotator so the antenna can rotate 180° without straining the cable or feedline. For dual parallel arrays, feedlines should be taped to the boom on either side of the rotator, with enough slack left to allow 180°...
