Using a crane for support, radome assembly starts with the top zenith panels. As the crane lifts these panels, new rows are added until the radome is completely assembled. Crane lift sling attachment radome points are usually changed to accommodate the partially completed structure. In contrast, the scaffolding procedure, Figure 2, starts with the radome base. When applicable, any base interface ring is first put in place by bolting it to the existing platform, replacement platform, foundation structural ring or tower.
Assembly starts at the base layer, progressing toward the radome top.
All bolts are torqued to proper settings. Typically, scaffolding is used as work platforms. When a crane is available, the bottom layers are assembled until the diameter of the antenna is circumscribed. At the end of each day, the radome is secured by nylon ropes. Equipment exposed to the weather is covered until radome water leak testing is completed.
