Tower array 109450
Tucson, Arizona · Pima County
Overview
A tower array element of 78 m (256 ft), structure 109450 has stood about 17 km (10 mi) from Tucson, AZ for about 44 years.
It is taller than 91.4% of the 1,789 registered structures in Arizona, placing it 155th statewide.
Vertical Bridge Cc AM, LLC holds the registration. Tower companies like this one lease space on their structures to multiple carriers, so the registered owner does not tell you which networks operate here.
At 78 m, the radio horizon for an antenna at the top of this structure works out to roughly 36 km (22.6 mi). That is a geometric limit for flat, unobstructed terrain — real coverage depends on transmit power, frequency, terrain and what is in the way.
The closest other registered structure is 26 m to the E. In total there are 15 other registered structures within 5 km.
The registration dates from the 1980s, part of the 1,789 structures on file for Arizona.

About this record
One element of a 3-tower array. Multi-tower arrays are typically AM broadcast antennas, where the towers work together to shape the signal in a particular direction.
Record 109450 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.
