RF101: Broadcast Terrestrial Transmission Systems course is an introductory survey of the RF fundamentals needed to successfully monitor a broadcast facility. The course is targeted to those with minimal or no background in RF and/or are relatively new to the field. It will also serve as a refresher for more seasoned engineers. Many come to the field of Broadcasting from varied backgrounds such as IT, electronic technicians or military vets, and find themselves immersed in the complexity of a broadcast facility needing to understand and work with the RF end of the system.  This multi-module course will present an overview of RF needed to understand the basics and make informed decisions.  RF101 modules will be presented in eight 1-1½ hour webinars, with the first, “Introduction to Radio Frequency (RF),” being presented on January 26, 2017 at 2 pm ET.

Module 1 of RF 101: Broadcast Terrestrial Transmission Systems is Jan. 26

This first webinar, Introduction to Radio Frequency (RF), will include the following topics: Definition of RF and Electromagnetic radiation and spectrum, Electric and magnetic fields, The Inverse Square Law and Attenuation of EM waves, Frequency bands and RF wave characteristics, Units of power: dB and dBm, History of RF, and Safety issues introduction: Exposure and limits.

The remaining modules will be presented over the coming months. Watch for further announcements.
