Hi all, During my regular inspection of my coaxial cables, I noticed 2 or 3 hard bumps along the length of the cable. These bumps or pimples, do not break through the outer jacket, but look as if they are on the verge of doing so. These bumps, or whatever, are small, about 1/8th inch or so. Any idea what they are, or what causes them? 73 Buddy WB4M
