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, MSHD
