4.5.2.
Refer to the Radome Assembly drawing for your system and the procedure below. It is best to have at least
TWO people sub-assembling the radome, one working from the inside and the other outside. Sub-assemble
the sections of the radome on a clean, flat location that is free of rocks & debris (ie concrete) to assure good
horizontal alignment of the panels.
Sub-assemble the bottom panels of the 144” Radome Assembly
If there are sufficient number of people available to each hold a panel while an additional person loosely
installs a bolt/nut high, mid and low on each flange, the bottom half of the radome can be assembled very
quickly. With 3 bolts loosely holding each flange the radome will then stand as a loose bowl and the extra 5
people can leave. Loosely install the rest of the hardware in each flange.
