Slide upper matching network bracket (160) onto base section

(BA). Place it tight against the fiberglass insulator. Insert one

2" screw (120) into bracket (160) and attach nut (87) as

shown in Figure E. Slide Matching Network screws into holes

on upper matching network bracket (160). Position bottom MN

bracket over captive screw in base section (BA) and secure

with #10 nut (220) and a #10 lock washer (233).

Secure MN to upper MN bracket (160) with two nuts (11)

and lock washer (941). Tighten screw in upper MN bracket

(160).

The radial rods may be inserted into the base section at any

time in the assembly process.

One at a time, place the stainless radial rods (32) into the

slots in the radial rings. Tighten the corresponding ring screws

as you work your way around the rings. The radial rings do

not have to touch each other to secure the radial rods properly.

Do not overtighten the screws. When all rods are secure,

tighten all hardware on the base section. Attach jumper strap

(428) to MN screw with nut (11) and lock washer (941).

Attach warning labels (326) as shown.
