Very heavy duty Azimuth rotator/controller

SKU: BIG-RAK Category: Feature: Brand: Only 1 left in stock





Medium to heavy duty antenna positioner in the same class as the M2 Orion 2800, HyGain TailTwister and Yaesu G-2800 but with advanced digital features and at an outstanding price.

Mechanical complexity is reduced to a minimum by utilizing a simple double worm gear drive system.  Position readout is sensed by a magnetic reed switch.  The controller has a full complement of features including digital readout.

Rotating torque is in the 2,800 to over 4850 lb-inch range, with between 12 and 24 volts to the motor. The 24 volt measured torque is 3,240 lb-inches (366 Newton meters).  This is significantly more than any other rotator in the same price range, and even higher than other rotators costing nearly twice as much (e.g., Yaesu G-2800 or Orion 2800).

Positioner (Rotator)

  •     Low voltage - high torque DC gear head motor
  •     Rotating torque/speed: 1,400 lb-in at 12v (120 sec) to 3240 lb-in at 24v (60 sec)
  •     Quiet and powerful self-braking action with double worm drive reduction
  •     Real steel housing and final worm drive - no soft pot metal or cast
  •     Uses inexpensive 4 conductor cable
  •     Sealed reed switch sensor technology for reliable all weather readout
  •     1 degree positioning accuracy - tight tolerances for minimal play
  •     Rated for large loads even when mounted outside the tower
  •     Designed for simple mounting to ~2" pipe mast - both ends
  •     Adaptors available to mate with other common rotator bolt patterns
  •     Coax can pass through centre of rotator - prevents cable damage


  • Manual, Automatic, Scanning, and Programmable modes
  • Digital readout with 1 degree resolution
  •  Large easy to read soft green LED display
  •  Computer interface via included serial cable, including Hygain, Yaesu and Orion emulation modes
  •  Low voltage DC operation from any 12 volt source (typically 2-5 amps)
  •  Ideal for camping, DXpeditions, VHF/UHF rovering
  •  Can be zeroed at any position to allow for installation inaccuracy or antenna mount slippage
  •  Generous overtravel (+/-180) with electronic limit
  •  Programmable limits ideal for side mount applications
  • Small front panel to simplify stacking several units takes up less valuable space
  • Optional mouse control with 6 user programmable presets

The BIG RAK 'in shack' controller

Rotator Cable - requires 4 cores, although we offer 7 and 8 core allows for additional control/switches, pre-amps,  etc.

All SPID rotators require an external power supply.

Typically they are run from the station 13.8v supply. For the larger rotators with sizable antennas, upto 8 amp would be required. In many cases a separate PSU from the rig is recommended, and start surge should be factored in.
