The site lies 13 km (8.0 mi) outside Semmes, which is characteristic of structures placed for terrain and line of sight rather than proximity to population.

About this record
A freestanding tower whose specific construction is not further specified in the registration.
Record 103911 is drawn from the FCC ASR weekly file dated 2026-08-23. The database covers structures that require registration — generally those over 200 ft or near airports — so shorter masts and small cells will not appear.
"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.
