1. Position the two 20” Unistrut channels on the backside of the RJU-2000 switch
box, aligning and centering the two center slots of the channel with the
mounting holes of the switch box. Fasten with the 1/4” hardware (4 each bolts,
split and flat washers).
2. Position the converters with fins down and mounting brackets facing upward,
leaving a gap between roughly the width of the RJU-2000 switch box (refer to
Figure D-3). Position and orient the channels, with switch box attached, onto the
converter brackets with the switch box between the converters. Ensure that all
items are oriented correctly and fasten with the 1/4” hardware (twelve each
bolts, split and flat washers).
Note: It may be necessary to loosen the hardware on the switch box in order to
align the mounting holes between the Unistrut channels and the converter
brackets.
3. Using a Spar support bracket as a guide, position two spring nuts in each of the
Unistrut channels. The threaded holes in the spring nuts must be aligned with the
holes in the Spar support brackets and should be centered in the Unistrut
channels.
4. Position the assembly on the Spar arm of the antenna (refer to Figure D-2) and
fasten the Spar support brackets to the spring nuts in the Unistrut with the 5/16”
hardware (4 each bolt, split and flat washer). Ensure that the assembly is
mounted in such a manner as to provide enough room for cabling and to avoid
interference to surrounding objects.
