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 T-2XD2 includes the DCU-2 Digital Automatic Controller and is intended 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.

The DCU-2 advanced digital controller can be used with any HAMs or Tailtwister rotators. Large, graphic LCD screen (1 3⁄8” W x 2 5⁄8” H) with large bright numbers and letters on an easy-to-the-eye blue background blends in with most modern stations. LCD displays rotator heading, external controller heading and even your callsign. DCU-2 has automatic or manual control. Dial in your heading with the internal control and press Rotate, the antenna will automatically rotate to your direction. Headings are in one degree increments. Left/right buttons allow manual control. More Advanced features: AutoBrake Release— No need to remember to release brake or release too soon — release time is automatic, settable 0-8 seconds. Coast feature allows for mass of the antenna to come to a stop in the right direction before the brake locks everything down. Coast delay cuts off the motor before reaching the selection — reduces overshoot due to antenna mass. Auto jogs make sure that the antenna is unlocked and free before turning begins. Its most helpful for older rotators with sticky brakes, auto control will jog the rotator backwards slightly before going in the proper direction, insuring that brake pressure is eased up enough to release. Fine beam heading touch-up is quick-and-easy with manual keys — no worrying about the brake. Offset feature allows display reset to indicate actual heading. Adjustable sleep mode 0-255 minutes. USB/RS232 ports allow computer-control of DCU-2. Ham Radio Deluxe, other compatibles. Field upgradeable firmware. 8.5″W x 4.3″H x 9″D. Requires 110V. See the DCU-2X for 220 VAC operation.
