The NCTI Installer Technician course focuses on maintaining reliability in the installed drop system. The electronic theory provides the foundation for understanding decibels, signal leakage detection and troubleshooting techniques. A basic mathematics review helps the student with equations and formulas relating to basic electronic theory and signal level. Also covered are topics on how to detect and troubleshoot signal leakage in the VHF and UHF frequency bands including LTE frequencies. The course concludes with the basic characteristics and functions of line extender amplifiers and a discussion of government regulations and ways to comply with industry rules.

Completion Time:

The estimated completion time for this course is 40 hours. The maximum allotted time is four months from enrollment.

Benefits:

  • correctly troubleshoot and maintain the installed drop system
