Monopole 603190
Near Baltimore, Maryland · Harford County
Overview
The FCC lists structure 603190 about 33 km (20 mi) from Baltimore, MD as a monopole. Overall height above ground is 48 m, or 158 ft.
Of the 76 structures registered about 33 km (20 mi) from Baltimore, MD, this is the 52nd tallest.
American Towers 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 48 m, the radio horizon for an antenna at the top of this structure works out to roughly 29 km (17.8 mi). That is a geometric limit for flat, unobstructed terrain — real coverage depends on transmit power, frequency, terrain and what is in the way.
Registration density around this point is 5 other structures within a 5 km radius.
The site lies 33 km (20 mi) outside Baltimore, 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.
