Castalia was an auxiliary (repeater) station on AT&T's first transcontinental microwave route, linking Birmingham, OH to the east and Gibsonburg, OH to the west.
Castalia's physical structure is a 133-foot type 3B concrete "silo" tower.
Like all of the stations on the transcontinental route, Castalia was originally equipped with KS-5759 delay-lens antennas. These were replaced by KS-15676 horn-reflector antennas, which increased route capacity by allowing the use of more frequencies and two polarizations.
