The FCC released a report & order detailing some rule changes that are very beneficial to AM radio stations, particularly those that employ directional arrays. While wireless licensees have long been required to analyze the impact of their tower construction on nearby AM antennas, provide advance notice to the AM licensee and, when indicated, detune their antenna structures, other services have not had this requirement. As a result, many towers have been built near AM antennas, producing pattern distortion and costing AM licensees as they deal with high monitor points and other effects of this distortion.

The rule changes make AM antenna protection universal across services, provide a mechanism for dealing with existing pattern interference, and provides for the use of moment-method modeling as the primary means of determining reradiation potential. In the webinar, Cris will review the new rules and discuss how they will impact AM broadcast stations.

Why You Should Attend

To learn how the changes the FCC has made to AM rules will affect you and your station. Knowing these changes will help you keep your station operate more efficiently and deal with pattern distortion from neighboring towers.
