Cable Television Technicians
Cable television technicians perform a wide range of duties in a variety of settings. Television cables usually follow the routes of telephone cables, running along poles in rural and suburban areas and through tunnels in cities. Working in tunnels and underground cable passageways, cable television technicians inspect cables for evidence of damage and corrosion. Using diagrams and blueprints, they trace cables to locate sites of signal breakdown. Technicians may also work at pole-mounted amplifiers, where they analyze the strength of incoming television signals, using field-strength meters and miniature television receivers to evaluate reception. At customers' homes, technicians service the terminal boxes, explain the workings of the cable system, answer questions, and respond to complaints that may indicate cable or equipment problems. When major problems arise, they repair or replace damaged or faulty cable systems.
