Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Radio, Cellular, and Tower Equipment Installers and Repairers

Military experience monitoring communications signal quality, isolating faults, and restoring equipment transfers to transmission-equipment testing and repair.

How to prepare: Complete hands-on training in transmission-component sweep testing and power, ground, and coaxial cable installation to build civilian installation skills beyond the documented military maintenance duties.

What the civilian work involves

Test operation of tower transmission components, using sweep testing tools or software.
Run appropriate power, ground, or coaxial cables.
Install all necessary transmission equipment components, including antennas or antenna mounts, surge arrestors, transmission lines, connectors, or tower-mounted amplifiers (TMAs).
