Step 4. Clip the cotter rings onto the
closed end of the wires. Secure the six cor-
ner latches on the reflector with the six 1/4"
(6.4 mm) nylon nuts and bolts supplied.
Suspending the Echomaster from a Spreader
Two small sheaves can be installed about 8" (20 cm) apart on the spreader, as
shown here:
Then, using a 3/16" (5 mm) braided dacron line as a halyard and the harness of the
Echomaster attached, the reflector can be hoisted to within 10" (25 cm) of the
spreader. Many other solutions are equally satisfactory; however, to minimize wear
and chafing on the suspension lines, we recommend the system shown here.
Although rotation and bouncing in the wind do not degrade Echomaster’s perfor-
mance, free-spinning in one direction and then the other can fray the support lines,
leading to possible breakage. To limit spinning, secure a tie line to the side, or add a
a “windvane tail” to a hole in one of the six corner latches of the reflector. The “wind-
vane tail” consists of a 1/8 to 3/16" (3.2–4.8 mm) line, extending 20–24" (50–60 cm).
It stabilizes the reflector as the wind increases.
