Core Skills

  • Communications troubleshooting in remote, austere environments
  • Satellite communications and data transmission knowledge
  • Radio waveforms and modulation techniques
  • Field expedient antenna principles

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

Maintaining expeditionary communications systems and applying knowledge of radio frequencies and field expedient antennas transfer directly to radio transmission equipment installation and troubleshooting.

How to prepare: Complete hands-on training in commercial antenna installation and transmission-component sweep testing to bridge from expeditionary systems to civilian equipment.

What the civilian work involves
  • Inspect completed work to ensure all hardware is tight, antennas are level, hangers are properly fastened, proper support is in place, or adequate weather proofing has been installed.
  • Test operation of tower transmission components, using sweep testing tools or software.
  • Install all necessary transmission equipment components, including antennas or antenna mounts, surge arrestors, transmission lines, connectors, or tower-mounted amplifiers (TMAs).
