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

Operating radio receivers within cryptologic collection systems provides equipment familiarity relevant to learning radio installation and testing.

How to prepare: Take a hands-on radio equipment installation course covering power, grounding, coaxial cabling, and transmission-component testing. Verified duties establish collection-system operation, not installation or repair experience.

What the civilian work involves
  • Run appropriate power, ground, or coaxial cables.
  • Test operation of tower transmission components, using sweep testing tools or software.
  • Read work orders, blueprints, plans, datasheets or site drawings to determine work to be done.
