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. RF101, Module 3 - Towers, Antennas and Transmission Systems will be presented Thursday, April 13, 2-3:15 p.m. EST.

Module 3 of RF 101:Towers, Antennas and Transmission Systems

This module continues the RF101 Series and covers these topics: transmission systems block diagram; common RF system componenets; antennas and terms; isotropic radiator; dipole and polarization; wavelength versus antenna size; variations on the dipole; and antenna gain introduction.  Join us for RF101: Module 3 Towers, Antennas and Transmission Systems.  Taught by Dennis Baldridge, CPBE, 8-VSB, AMD, DRB, CBNT, the webinar continues the RF101 training.
