About this record
A freestanding tower whose specific construction is not further specified in the registration.
All measurements shown are taken from FCC registration 620819. Height is the overall height above ground including any antennas and lightning rod, which is why it can exceed the height of the supporting structure alone.
"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.
