2. To assure uniform drilling of any one type element set, the following procedure is

recommended. Select four (4) of the previously prepared arms and line them up side by

side with the butt end against a solid stop to assure common length and alignment.

Butt end

REMEMBER to allow for drilling THROUGH the arm by spacing the arm above the work

surface. Pieces of scrap wood positioned along the length of the arms will provide the

necessary clearance. Orient the arm assembly screws vertically and clamp the arms to

prevent them accidentally turning during the drilling process. Now using the dimensions in

Table III and measuring from the "butt" end mark each arm for each band. Recheck your

measurements and then proceed to drill through both sides of the arm with a 1/8" (3.1 mm)

drill bit. Mark the arms per their function (REFL, DRV, D1, D2) and set them aside.

4. The wire has been spooled in a relatively large diameter to minimize "curl" and reduce

the chance of kinking. The wire bundles are marked for as follows – Reflectors &

Driven Elements (2el, 3bands) WARC band Reflectors and Driven Elements

(12m/17m) are separately packaged. There are additional packages of wire for the

Directors as applicable. All wire lengths should be carefully un-spooled by rolling the

coil of wire in the appropriate direction.

A convenient device for helping to keep the wire manageable is a

plastic water "Pail" inverted. Its conical shape allows the wire spool to

slip over while providing support for the bundle.

5. A suggested method for winding accurate elements is to fabricate

a temporary winding jig consisting of a few lengths of 1" x 4" wood board stock for a

total length of about 20 feet (6 m). Mark the center of this board, and 1-1/4" (3 cm) on

either side. The center is used for Reflectors and Directors, and the two separated

points are for Driven Elements. Regular number 6pd finishing nails can be driven into

the board leaving about 1" or so protruding.
