Worldcast Systems - Radio & TV Broadcast Solutions


The new Ecreso Switch Controller (ESC) is a single, centralized unit to control and monitor RF switches at transmitter sites for analogue or digital Radio or TV. Reliable, robust, and easy-to-use, it facilitates and secures maintenance and antenna switching operations while maintaining high uptime and staff safety. 

Highly configurable depending on the number of transmitters, antennas, patches or switches installed on-site, it also provides constant system control and monitoring, locally and remotely.  


In a complex, high-risk environment for technical staff, there is a need for a system to facilitate & secure maintenance and antenna switching operations

Success Story

In the context of the TV repack operation in the United States, two WorldCast Group companies, WorldCast Systems and CONNECT, have been selected to develop and supply an Antenna Switch Controller System along with a unified monitoring platform for the RF operations (DTV and FM) of Sutro Tower. Overlooking San Francisco from its 977-foot-high steel tower, Sutro Tower is a major broadcast site delivering clear signals for television and radio stations throughout the San Francisco Bay Area.
