7. Remove the foam dielectric from the inner conductor:
1. Use a knife to cut the foam dielectric flush with the outer conductor, to the depth of the inner
conductor, then cut along the length of the inner conductor several times, until all the foam
dielectric is removed; see Figure 75.
2. Use a knife to carefully scrape any remaining dielectric foam adhesive from the inner conductor.
Be careful not to damage the copper coating on the inner conductor.

8. Trim the inner conductor:
1. Add the inner conductor cutting guide, as shown in Figure 76.
2. Use a fine-tooth saw to trim the inner conductor flush with the cutting guide, as shown in Figure
77.
3. File the outer conductor to the specifications shown in Figure 77.
4. Use a clean wire brush to remove any debris from the foam dielectric.
