lines can develop holes due to rifle bullets, chafing, lightning
strikes, or arcing due to high RF fields from transmitting antennas.
These can often be repaired without taking down the line by such
methods as soldering, glued on patches, or rubber patches. In this case
arcing burned a large hole in this 3 inch coaxial cable. The
polyethylene jacket was removed and the area cleaned around the damaged
area. A piece of corrugated copper was cut from an old piece of the
same cable and glued on using JB Weld. The area was taped up to finish
the repair. The repaired cable holds pressure and there is negligible
difference in the transmission characteristics at FM radio frequencies.
