Overview

FM stations sharing common infrastructure, towers and antennas, have challenges to overcome in order to be compliant with the FCC’s 47 CFR Part 73 rules, 80 dB suppression from the carrier amplitude, regarding out of licensed channel emissions. Coupled energy between transmitters can cause unwanted intermodulation products that exceed those rules.  FM filters have been designed to eliminate the creation of those products in both small and large systems. Design aspects of filters will be discussed including the use of loops, iris and direct couplings. This webinar will cover the types of filters used such as notch and bandpass filtering. This presentation will also address the use of commonly used technologies for emissions control and channel combining for shared antenna systems. Custom filter solutions will be covered that isolate FM signals from AM towers and combine analog FM and digital IBOC when transmitter technologies are not used.
