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.
T2X Tailtwister Series II
for large medium antenna arrays up to 20 square foot wind load
The T2X is the base model for use with 120V power. The Tailtwister is one of the most popular rotators in the Hygain product line. It has been the standard to what competing rotators have tried to match since the TX-2 Tailtwister rotor was introduced.
The T2X Tailtwister Series II Rotator is for large medium antenna arrays up to 20 square foot wind load. Its wind load with mast adapter is 10 square feet. It has 1000 inches-pounds in turning power and 9000 inches-pounds in brake power. The effective movement in the tower is 3400 feet-pounds.
A new 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. T2X features a new low temperature grease which permits normal operation to -3O° F. New alloy ring gear has tensile strength of 100,000 psi for max reliability.
The indicator potentiometer has been improved for greater reliability. A silver-plated relay contact point makes for smooth traveling and more reliable contact between the pot strip and wiper arm gives years longer life on these important, internal components.
New water-tight AMP detachable twist-and-lock connectors at the rotator base and an 8-pin plug at the control box make it easy to hook up. Rotator has a triple bearing race with 138 ball bearings for large load bearing strength. Electric locking steel wedge brake prevents wind induced antenna movement.
The control box features a North or South center of rotation scale on meter and low voltage control for safe operation.
Clamp plate and stainless steel mounting hardware is included for a up to a 2 1/16 inch mast.

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.
Adjustable LCD sleep time.
