2.1.2 Fabricating signal cable S03-75
1. Remove the vinyl sheath by 450 mm.
2. Slide the clamping ring, washer, rubber gasket
and washer onto the signal cable in that order.
3. Unravel the outer shield to expose the cores in
the outer layer. Then, unravel the inner shield to
expose the cores in the inner layer. Label all
inner cores to aid in identification.
4. Attach EMI cores to all inner cores and all outer
cores, and bind them with cable ties, etc. Note
that there are two types of the EMI cores, thick
and thin.
5. Trim each core (except coaxial wire) considering
its location on the terminal board in the antenna
unit.
6. Trim the inner and outer shields leaving 500 mm
each. Twist shields together and attach crimp-on
lug FV5.5-4 (blue, 4).
7. Remove insulation of each core by about 6 mm.
Fix crimp-on lug FV1.25-3 (red, 3) to each core.
8. Fabricate the coaxial cable. Make the length 10
mm longer than the shield to prevent wire strain.
Attach crimp-on lug FVD1.25-3 (red, 3) to
coaxial cable.
