The towers, called Shoreview Towers by local residents, are owned by Telefarm, Inc., a joint venture of Twin Cities broadcasters CBS Television Stations (WCCO channel 4), Hubbard Broadcasting (KSTP channel 5, KSTC channel 5.2, KSTP-FM 94.5 FM, and KTMY 107.1 FM), and Tegna (KARE channel 11) for the transmission of digital television and FM radio throughout the Greater Twin Cities.
Along with Sinclair Broadcast Group's WUCW (channel 23), Minnesota Public Radio flagship station KNOW-FM (91.1 MHz) are additional tenants on the tower.
[1] The towers were upgraded at the turn of the century to support digital TV transmitters to meet Federal Communications Commission requirements.
Because each antenna assembly weighs many tons, the towers had to be strengthened.
Work took longer than expected, and KSTP notably used its original broadcast tower along University Avenue in Saint Paul, Minnesota for digital transmission for about a year starting in late 1999 before construction was finished.
