WGBO-DT is one of only two full-power television stations in the Chicago market (the other being PBS member station WYCC, channel 20) which maintain transmitter facilities atop the John Hancock Center. Most of the market's other television stations operate their transmitters atop the Willis Tower, although WPVN-CD (channel 24) transmits its signal from the Trump International Hotel and Tower. On September 24, 2012, WGBO filed an application to move its transmitter to the Willis Tower at 650 kW; the FCC granted the construction permit to build the Willis Tower transmitter on October 23.
