4 - Feed System Assembly
Figure F shows the steps for feed system assembly. Identify the parts
required using the Feed System Subassembly Parts List. Position the
Matching Network (MNX) on the bottom of the X7 boom on the reflector
side of the 40 meter driven element. Space the MNX feed screws 1"(2.5
cm) from the U-Channel bracket (707). Secure the MNX to the boom
using two worm clamps (81). Attach the Feed Straps (FS) to the two
screws on the MNX and the two driven element screws with the hardware
shown. Position the Feed Straps away from the U-Channel bracket (707).
