White Oak is a Type 4A concrete tower, 147 feet tall, constructed in late 1949 by the National Concrete Fireproofing Company, Cleveland, using the fixed form method of construction. The company also built 16 other concrete towers for the New York to Chicago section of the transcontinental microwave route at about the same time.
The original usage of these towers was to provide network television programming to Cincinnatti. This microwave route used TD-2 equipment and was not directly connected to the backbone microwave transcontinental and coax route by microwave radio, instead L1 coax was installed at about the same time from Toledo to bring the television signals to Dayton, from there one branch of the microwave route carried the signal through Springfield and Catawba to Columbus, and the other branch carried the signal through Springboro and White Oak to Cincinnati.
White Oak originally had delay lens antennas on the roof, at a later point a steel tower was installed on the roof to support KS type horn antennas, replacing the delay lens antennas. The space diversity receive antenna at White Oak is installed upside down, an unusual arrangement.
