SPID-BIG RAK - Azimuth Rotator

SPID Big RAK

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

Controller

• 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
