Assembly and
Installation of Antenna on the site
(1) Obtain four saw horses or other supports that will hold the complete antenna
horizontally at a convenient working height and place them in the assembly area. The
assembly area must be a cleared working space approximately 40 feet long and 20
feet wide.
(2) Support the base section (Item 1, Table 3.1) on two of the saw horses.
(3) Support the top section (Item 2, Table 3.1) on the other two saw horses so that the two
sections lie in the same straight line.
(4) Make sure the threads of the male and female ferrule on the base and top sections are
clear of foreign material and not damaged.
(5) Assemble the second antenna section onto the base section and tighten to align the
arrows (if applied) at the joint using the strap wrench supplied (Item 3, Table 3.1).
Install the set-screws and seal with the sealant provided (items 4 and 6). A final
torque between 65-85 in-lbs is acceptable for the set-screws.
(6) The antenna is now ready to be raised to its final position. Raise antenna into position
using a gin pole and winch or a bucket truck or a crane.
