horizontally. Place a piece of scrap wood over the very end of the top
section of the pole and gently hammer on the scrap wood to fit the two
halves together. A 1.27 cm (1/2 in) gap between the top and bottom pole
sections is acceptable. Lay the assembled pole on the ground next to the
concrete foundation.
3. Cut and save a 9 inch piece of 12 AWG ground wire from the 12 foot
length provided. This will be used later to attach the enclosure ground to
the lightning rod assembly (reference FIGURE 2-6).
4. Thread communication cable, power cable with connector ends of cable
out the top of tower, and grounding wire through the tower and conduit.
Electrical fish tape will help. Leave approximately two feet of the
supplied power and communication cable hanging out of the top of the
pole. Secure all wiring so it doesn’t slip back down through the pole.
Solar panel and RF options will not have power or communication
cables.
5. Place the white tower cap over the tower end.
6. Raise the tower on a still day. Place a washer on top of the two nuts on
each foundation bolt. Taking great care not to damage cables between the
tower and conduit, raise the tower and lower it onto the conduit and
mounting bolts. Install a washer and nut on each bolt and hand tighten.
Check plumb of the tower by placing a level on the north and east sides of
the lower tower section. Adjust the topmost of the two lower nuts
(leveling nut) on each bolt as necessary. When plumb is established, lock
the leveling nut in place by tightening the lowest nut against it. Tighten
the three top nuts with the wrench.
