Installing

The following steps are for mounting the

ABBIOOO

antenna using the

standard Delta loop model which needs a center support and two end

supports. Mount the antenna clear of all metal objects and power

lines. It should be as high as possible and as much in the clear as pos-

sible.

Carefully unwind the

30Am

coax cable and lay it straight out

from the center support tower. The cable should be free and

straight. Do not allow kinks in the coaxial cable.

Attach the pull-up cable to the eyebolt on the transformer and

pull the transformer up to an easy working height (1.5m to 1.8m

above the ground). See Figure 6.

Very carefully unwind the stainless steel cables. This cable will

twist badly if not done carefully. As you layout the wire,

unwind and walk away from the free end. This cable must NOT

be kinked. Lay each stainless steel cable out and away from the

center support structure in a direction towards the intended mast

locations.

sing the cable hooks, attach the end of the stainless steel cable

to the eyebolts on the side of the transformer. Install the solder

lug onto the #10 bolts located on each side of the transformer.

Tighten the nuts securely. See Figure 7.

Located on each stainless steel wire is a slip insulator. Slide this

insulator to the approximate center of each stainless steel wire.

Vsing the V-bolts mounted on the terminating network (large

heat sink), mount the terminating network on the support struc-

ture at the same height as the end mounting supports. Connect

the transformer with the short coax to the matching network.

Screw on the coax connector and tape the connector for envi-

ronmental protection.

Carefully bring each end of the stainless steel cable that was

laid out from the center support and attach it to the transformer

mentioned in step 6 (see Figure 8). Attach each end as in Figure

Raise the top transformer to the top of the support structure and

secure. Tie the nylon cords to each of the sliding insulators on

the outside of the stainless steel wires. Pull the nylon lines and

attach to the end support structures. Pull these fairly tight as to

remove most of the slack in the stainless steel wires.
