2.1.4 Install High Power Outdoor SSPA Modules
Each of the uni-strut frame assemblies has slots to install up to four (4) High Power
Outdoor SSPA units. Identification stickers are affixed to the frame adjacent to the
space where the matching SSPA module should be installed. All SSPA modules are
labeled. When installing the SSPAs, make sure to match SSPAs from the same sys-
tem together, and insert the corresponding SSPA Module to its position in the uni-strut
frame. This will reduce the need to optimize the system output at initial startup.
Caution!
Each SSPA weighs in excess of 100 lbs. (45.5 kg). At least
two persons are required to install each SSPA. Lift the SSPA by the han-
dles on either side. Do not lift from the RF Output waveguide flange or by
the connectors.
Aluminum supports are attached to each High Power Outdoor SSPA module. The am-
plifiers should be slid along the uni-strut rails at the opening opposite the waveguide
array. The amplifier should be positioned so the RF Output flange is inserted into the
opening, with the SSPA supports at the bottom. See
Figure 2-10
.
Begin with the top-most amplifier in each system (SSPA 1.1 or SSPA 2.1). Carefully
slide the amplifier along the uni-strut rail until the support nears the square washer
stop. Adjust the amplifier side-to-side until the RF Output waveguide flange aligns with
the waveguide array. Insert an appropriately sized half gasket (provided) between the
High Power Outdoor SSPA module RF output and the waveguide assembly.
