Monopole 603455
Indianapolis, Indiana · Marion County
Overview
The FCC lists structure 603455 about 12 km (7.5 mi) from Indianapolis, IN as a monopole. Overall height above ground is 43 m, or 140 ft.
It is taller than 11.9% of the 3,767 registered structures in Indiana, placing it 3319th statewide.
Crown Castle South 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 43 m, the radio horizon for an antenna at the top of this structure works out to roughly 27 km (16.7 mi). That is a geometric limit for flat, unobstructed terrain — real coverage depends on transmit power, frequency, terrain and what is in the way.
This is a dense cluster: 18 other registered structures fall within 5 km, the closest just 1.4 km (0.8 mi) to the NE.
The site lies 12 km (7.5 mi) outside Indianapolis, which is characteristic of structures placed for terrain and line of sight rather than proximity to population.

About this record
A single tubular shaft. Cheaper to permit in built-up areas because it takes little ground space and reads as less industrial than lattice.
This page summarises FCC ASR record 603455, from the weekly file dated 2026-08-23. Rankings and comparisons on this page are calculated by Pylon Plans from the full national dataset, not supplied by the FCC.
"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.
