Many parts to each unit..

Assembling an element housing unit (EHU) prior to installation.

The interior of a SteppIR Element Housing Unit (EHU) with stepper motor that drives copper-beryllium tapes in and out of the hollow antenna element tubes. The tapes are the radiating/active elements of the Yagi beam antenna. This SteppIR antenna is able to be resonant anywhere between 6.5 Mhz and 54 Mhz by adjusting the lengths of the Beryllium tapes. The tapes are wound on the spools that are seen in the picture using the cogged wheel that engage holes punched into the tapes. Cogged wheel is driven by a stepper motor, which has absolute positioning capability. The computerized controller knows how far to position out the tapes in the driver, reflector and director tubes for any given frequency.

Gary (W7TYQ) Dave (W7DJE) and Peter (AC7SB) attach the reflector Return Element Support to the boom.

Peter Rosenberg (AC7SB) from Fall City WA joins the antenna assembly team. Steve (WA7DUH), Peter and Gary (W7TYQ) apply anti-sieze compound to the staddles that will be used for one of the Return Element fixtures. Liberal use of anti-sieze compound is critical because of the many dissimilar metals used in both the antenna and hazer (aluminum, stainless steel hardware and galvanized steel.)
