A.1 Suggested Procedure For Cutting And Soldering
Transmission Line
The purpose for this procedure is to provide guidelines for field cutting and soldering of
RF transmission line used to interconnect the transmitter to the RF system.
Try to cut and flange the longest pieces first. Complete one run at a time in order to avoid
accumulated errors. (i.e.: Cut, solder, and hang line from antenna port of Bandpass filter
to patch panel. Then cut, solder, and hang line from the Amplifier output to the input port
of the bandpasss filter.)
Listed in Table A-1 are some tools and materials that have proven effective for RF Feed
Line Construction.
A.2 Transmission Line Cutting and Flange Soldering
Procedure
a. Determine the flange-face to flange-face length of the transmission line run
needed. (If the run includes an elbow, see Figure A-2 to determine the elbow
length.)
b. Subtract twice the cutback dimension of the flange. This dimension varies with
flange manufacturer. See Figure A-1. Using the suggested methods for cutting the
line given in paragraph a.3, cut the outer conductor to the length just calculated.
c. If holes in the outer conductor are needed for directional couplers, tuning paddles,
etc. they should be added now with the holes properly deburred.
d. Using the suggested techniques for installing the flanges given in paragraph A.4
Soldering Transmission Line Flanges, solder a flange to each end of the outer
conductor.
