New! T2X and HAM-IV Pulse Rotator Improvement


HAM and T2X series of rotators have been improved adding a digital pulse counter to the rotators and digital controllers. Older rotators used a specially designed expensive potentiometer to determine antenna heading. Over time the pot wiper contacts get intermittent and noisy. This new design uses a special high temperature rare earth magnet and a reliable reed switch to count the rotations of one of the gears in the drive assembly. DCU-2 and DCU-3 have circuitry built-in to count the pulses and accurately determine the heading of the rotator to +/- 1 degree with repeatable accuracy. With the new pulse mode the noise and intermittent pot problems are no longer an issue. Older rotators can be retrofitted with the new gear and pulse board. Older DCU2 and DCU3 controllers will need a modification to the wiring and a firmware update that can be done in the field. The pulse mode is not compatible with the DCU-1 or the older controllers that have analog meters in them. Call Hy-Gain for more details! 662-323-9538.



HAM-IV is the most popular rotator in the world ! Its solidly constructed, has been time-tested and proven for over twenty years.

HAM-IV is for medium communications arrays up to 15 square feet wind load area (7.5 sq. ft. with mast adapter). It has 800 inches-lbs. turning power and 5000 inches-lbs. brake power.

Automatic 5-second brake delay insures that the rotator is fully stopped before the brake is engaged. No more accidentally engaging the brake while the rotator is in movement.

New Test/Calibrate function. New low temperature grease permits normal operation down to -30F. New alloy ring gear gives extra strength to 100,000 PSI for maximum reliability.

New indicator potentiometer has been improved for greater reliability. Silver-plated relay contact point makes for smooth traveling and more reliable contact between pot strip and wiper arm - gives years longer life span on these important, internal components.

Detachable 8 pin latching Cinch connectors make easy removal at rotator and 8 pin plug at controller. Dual 98 ball bearing race for load bearing strength and electric locking steel wedge brake prevents wind induced antenna movement. North or South center of rotation scale on meter, low voltage control, max mast size 2 1/16.110 VAC.

Order HAM-IVX for 220 VAC operation. Optional lower mast support, MSHD

DCU-3 Programmable Rotator Controller



6 Programmable memories; Point & shoot and manual control!





DCU-3 Digital Controllers feature six presets for beam headings, 1 degree accuracy and gives you fully automatic or manual control of your HAM or Tailtwister Rotators.Dial in your beam heading and press the rotate button or let Ham Radio Deluxe (or other) control your DCU-3. Your antenna automatically rotates to desired direction precisely and safely. First,DCU-3 makes sure your antenna is free and safely unlocked before turning begins and then turns off
your motor before your antenna reaches its finaldestination. Your antenna gently coasts to a stop before the brake locks. Greatly reduces potentially damaging overshoot. Fine tuning and full manual control is effortless with automated Left and Right direction buttons - - no more worrying about manually releasing and relocking thebrake. Brake automatically releases before fine tuning begins and relocks after fine tuning is completed. Bright blue LCD displays actual, dial-in beam, and computer controlled beam headings in one degree increments and your call sign. AutoBrake Release - no need to remember to release brake or release too soon release time is automatic 0-8 seconds.

Coast feature allows antenna to gently stop be-fore brake locks. Adjustable coast delay (0-10 degrees) turns off motor before antenna reaches its final destination to reduce potentially damaging overshoot. AutoJog unlocks and frees antenna before turning -- great for older rotators with "sticky" brakes. It jogs rotator backwards slightly to ease brake pressure enough to release. Offset feature allows you to calibrate display to show actual beam heading.

USB/RS-232 ports.

Adjustable LCD sleep time.

Field upgradeable.
