In this article, the author talks about the role and functions of a tower technician. A tower technician climbs up the face of telecommunications towers to remove, install, test, maintain, and repair a variety of equipment--from antennas to light bulbs. Tower technicians also build shelters and radiofrequency shields for electronic equipment, lay coaxial and fiber optic cables, and remove pests and weeds. Sometimes, they set supports and stack construction pieces to build the tower itself. Many tower technicians do not work in the occupation long. Some find the work too dangerous, can't cope with the stress of the climbs, or don't like the lengthy travel schedule. Others work in the field temporarily while looking for another job. Consequently, experienced tower technicians often earn excellent job security and are competitively recruited by different companies. Many also find that mastering telecommunications line technologies is exciting and rewarding.
