Maryland cell towers at a glance
The FCC records list 1,240 cell towers and other antenna sites in Maryland: every registered antenna structure that is built and still standing, plus the licensed cellular transmitter sites too short to need registration. That ranks Maryland 33rd of the 51 states and DC by number of registered sites. The most common structure is the tower, with 438 sites (35%). Baltimore has the most listed sites of any city, at 73.

Carriers on the record in Maryland
Verizon is named on the most Maryland sites, 87 of them (7.0%). A carrier is named only when it owns the structure or its cellular licence lists the site, so these counts are a floor, not a total. Most towers in Maryland are owned by tower companies that rent space to several carriers without naming them.
| Carrier | Sites naming it | Share of Maryland sites |
|---|---|---|
| Verizon | 87 | 7.0% |
| AT&T | 75 | 6.0% |
| T-Mobile | 20 | 1.6% |

What is not counted
FCC registration is required only for structures over 200 feet or near airports, so shorter monopoles, rooftop antennas and small cells in Maryland are mostly missing unless a cellular licence lists them. Why a tower is missing from the map explains the gap. The data is rebuilt monthly from the FCC's bulk files.
