The HX-5bi Hex-Beam is 5-band arry covering 10-12-15-17-20 meters. The primary design goal are convenience of instant band-change, economy of a single arry with a single support and feed system, durability of known design, and legal limit capability. The Hex Beam is a new approach to beam design. The creative spark for its hexagonal configuration came from the snowflake that forms from its center outward,forms in a planer fashion, and forms in 60 degree segments. These phenomenta established the foundation for the controlled field concept used in developing this beam. With the Hex Beam, two intense flattened fields are phased and coupled to provide a high level of performance in a compact package. Though the completed arry is half the normal size, this Hex beam's elements are full-size. No loading devices are used. Its small and its enhanced performance at low heights makes it great in senstive locations. The arry is fed with a 50 ohm line and is built to handle 1500 watts with a near zero wind load.

The Ham-IV rotator consists of a bell type rotator and a metered control unit. The Ham-IV is intended for in-tower mounting on the base plate within the antenna tower. The HAM-IV is used for medium communication arrays up to 15 square feet wind load area. It has 800 inches lbs. turning power and 5000 inches-lbs. brake power. Automatic 5-second brake delay insures the rotor is fully stopped before the brake is engaged. No more accidentally engaging the brake while the rotor is in movement. Low temperature grease permits normal operation down to -30 degrees F. Alloy ring gear gives extra strength to 100,000 PSI for maximum 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. Dual 98 ball bearing race for load bearing strength and electric locking steel wedge brake prevents wind induced antenna movement.
