About this record
One element of a 2-tower array. Multi-tower arrays are typically AM broadcast antennas, where the towers work together to shape the signal in a particular direction.
These figures come from the FCC's Antenna Structure Registration database, filed under registration 119881. Heights and coordinates are as submitted by the registrant, not independently surveyed.
"Owner" is the entity that registered the structure, usually a tower company such as American Tower or Crown Castle. It does not indicate which carriers operate equipment on the structure.
