Ham-VIIP Description     Hide

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 ! It’s 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 -30°F. 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 clamp, Model MSHD.
