Instructions:

the main spool. Allow enough connecting wire at the start, wrap around the nails so as to

have four (4) sides and finish with a "tail" of connecting wire – now cut the wire.

Elements should also be clearly identified, i.e., 10 mtr. driven ele.; 10 mtr. Refl. Ele.; 10 mtr.

director, etc., as required, and the corners can be marked with paint or marking pen while

still on the winding jig. These Corner markings can be useful in aligning the element

squarely.

There are several methods of assembling and erecting large antennas such as the SKYMASTER, and they

are dependant on the type of supporting structure (Tower), space available, clearance from surrounding

objects and other mechanical aides and helpers. The exact method will be left up to the assembler, and the

following are general requirements for completing the antenna assembly and do not necessarily address

specific erecting procedures.

Choose a level area that will accommodate a 17 X 17-ft square with extra working

room around all sides. Lay one of the end spider castings in the center of this area with

"troughs" facing upward. Lay four of the assembled spreader arms, one in each of the

depressed troughs. Be sure to orient the drilled holes now horizontally to facilitate element

wire assembly. Fasten each spreader arm to the spider using two stainless steel worm

gear clamps. One clamp is positioned near the butt of the spreader arm and should seat

between two small "buttons" on the underside of the spider spoke. The other clamp is

placed near the outer end of the spider spoke and should seat into a depression in the

underside of the spoke. DO NOT TIGHTEN COMPLETELY AT THIS TIME.

8. Assembly of the Boom

The boom for the 3 element Quad is two equal length pieces, coupled together with an

"split" insert section about 17" long. these are coupled together and secured with four (8)

#12 SS Screws.

Next the Bridge Truss Eyebolts must be installed at the pre-drilled points near the ends of

the boom. The "eye" should be topside, and apply the lock washer and tighten the nuts

again just until the washer is compressed. This completes the boom assembly.

9. Element Spacing and Placement:

The REFLECTOR Assembly, is placed at the end of the boom, as shown in Figure 4.

The DRIVEN ELEMENT is placed at the 10 ft. mark , and The DIRECTOR is at the

other end of the boom. After the assemblies are in place on the boom they should be

rotated and aligned so that all bottom element wires are parallel to the ground.
