Hy-Gain Ham-IV Antenna Rotator

Hy-Gain Ham-IV Antenna Rotator



Worldwide renowned antenna rotators for up to 2 m2 antenna surface.

HyGain antenna rotators are constructed with double or triple ball bearings for maximum stability and have electro-mechanical brakes which blocks the gear shaft, preventing the antenna to turn in strong winds. When rotating the antenna the brake is opened automatically and closed again (delayed) after reaching the final position.

The rotators are designed for installation on a flat surface (rotator platform), for mounting on a tube mast optional clamps are required. Solid aluminum die-cast case, precision tooled gear wheels, all mounting hardware stainless steel. Max. diameter for tubular antenna mast is 52mm.

The rotators are avaiblabe with two different control units:

The included analog unit has push buttons for direction and brake and an illuminated analog instrument for direction control.

The optional DCU-2 is a digital control unit, suitable for all HyGain rotators like the HAM-IV, T2X Tailtwister etc. A large LC display shows the currect antenna direction in degrees and as compass heading. Additionally the reverse direction from the other station to your location is displayed, along with your callsign. The easy to read, blue LC display has white lettering, the size is 35 x 66mm.

To facilitate the safe and precise rotation also of large antenna systems, the DCU-2 controller uses various methods for positioning. A brake, as it is used on some rotators, will be released and closed again, but only when the final position has been reached. The motor is stopped early, before reaching the final position. This reduces unnecessary load on the rotator and overshoot of the inert antenna.The DCU-2 control unit is equipped with both, a serial and an USB interface. This allows easy integration of the rotator into the station. The rotator can be directly controlled by Ham Radio Deluxe or similiar programs.

The DCU-2 sizes are 215 x 110 x 228mm (WxHxD).Two different models availabe:

HAM-IV for up to 1,6m2 antenna surface.
