ERI AXIOM™ Master FM Antenna on the IDS Center in Minneapolis

Located in downtown Minneapolis the communication towers on top of the IDS Center, 910-feet (277-meters), are the highest point in the State of Minnesota. ERI provided a 12-Bay AXIOM Master FM Antenna which serves as a combiner auxiliary FM antenna system for a number of major FM radio stations who formerly broadcast from this as their main transmitter site. They now use the IDS as a backup in case their primary location in Shoreview, Minnesota were to fail or when shut down for maintenance. The AXIOM Master FM Antenna is a broadband side mounted antenna that can be configured to handle a combined power levels up to 240 kilowatts. The communication spires on top of the building tower to 910 feet (277.3 m), making them the highest point in Minneapolis. The top of the IDS is also used for microwave transmission and reception by WCCO-TV, KSTP-TV, KMSP-TV, and KARE news trucks, in order to relay video to their stations.
