What is it called when two or more separate companies' antennas are located on one structure?

• A. Co-Locate
• B. Shared Tower
• C. Joint Tower
• D. Coexist

Answer: (A)

Sharing a single structure among multiple carriers is called co-location. This means antennas from different companies are mounted on the same tower or asset, allowing each operator to use the shared site while keeping their own equipment and radio gear. Co-location helps spread the cost of the tower, maintenance, and backhaul among tenants and speeds up deployment since the structure is already in place.

Other terms don’t fit as precisely. “Shared Tower” describes the idea but isn’t the standard industry term used to denote the practice of multiple tenants on one structure. “Joint Tower” isn’t a common term for this arrangement, and “coexist” just means existing together without specifying shared infrastructure.
