How do I find cell towers near me?

Enter your address above or click "Locate Me" to see all cell towers and power grid infrastructure within range of your location. The map shows tower positions, transmission lines, substations, and exact distances.

How many cell towers are in the US?

Our database covers over 570,000 cell transmitter sites across the United States, spanning 3G, 4G LTE, and 5G networks. The map is built on OpenCelliD, the world's largest open database of observed cell transmitters, combined with power grid data from DHS HIFLD and new tower construction filings from the FCC, synced daily.

Does this map include 5G towers?

Yes. Our map includes all registered tower types: legacy 3G, 4G LTE, and 5G networks. 5G towers are often smaller and more numerous, especially in urban areas.

What is EMF exposure?

EMF (electromagnetic field) exposure comes from two main sources: RF (radio frequency) radiation from cell towers and wireless infrastructure, and ELF (extremely low frequency) fields from power grid infrastructure like transmission lines and substations. Our EMF score combines both into a single 0-100 rating.

How is the EMF score calculated?

The EMF score (0-100) combines two sub-scores: an RF score based on cell tower count, proximity, and power levels within 2 miles, and an ELF score based on transmission lines and substations within 1 mile. The combined score is weighted toward whichever source contributes more exposure at your location.

What is the difference between RF and ELF?

RF (radio frequency) comes from wireless infrastructure like cell towers and 5G antennas. ELF (extremely low frequency) comes from power grid infrastructure like high-voltage transmission lines and substations. Both contribute to your overall EMF exposure, but from different sources and at different frequencies.

What is RF radiation from cell towers?

Cell towers emit radio frequency (RF) radiation to transmit cellular signals. RF exposure decreases significantly with distance — doubling your distance from a tower reduces exposure by 75%.

How close is too close to a cell tower?

There's no official "safe distance" as regulations vary. However, EMF exposure drops rapidly with distance. Most research focuses on locations within 300-400 meters of towers. Our map shows exact distances so you can make informed decisions.

Should I check for cell towers before buying a house?

Yes. Cell tower and power line proximity can affect both EMF exposure and property values. Use our map to check any address before buying or renting. Compare EMF scores between properties to make an informed decision.

How accurate is this cell tower map?

Our cell tower data comes from OpenCelliD, a crowdsourced database built from hundreds of millions of real-world signal observations. Tower positions are estimates and are typically accurate to within a few hundred meters. Power grid data comes from the DHS HIFLD program, and new tower construction filings come directly from the FCC's Antenna Structure Registration database, synced daily. See our methodology page for full details.

Check EMF Exposure at Any Address

Q: What is ELF exposure from power lines?

ELF (extremely low frequency) fields are produced by high-voltage transmission lines, substations, and transformers. ELF exposure drops quickly with distance but can be significant for homes within a few hundred meters of these structures. Our map shows all nearby power grid infrastructure and calculates an ELF sub-score.

Understanding EMF, RF & ELF

What is EMF?

EMF (electromagnetic fields) are invisible fields of energy produced by electrically charged objects. They are emitted by both wireless devices like cell towers and wired infrastructure like power lines.

Our EMF score combines RF and ELF exposure into a single 0-100 rating, giving you a complete picture of the electromagnetic environment at any location.

Why it matters: Growing research links prolonged EMF exposure to sleep disruption, stress responses, and other biological effects. Knowing your EMF level is the first step toward making informed decisions.

What is RF?

RF (radio frequency) radiation is emitted by wireless communication infrastructure including cell towers, 5G antennas, and broadcast towers. RF exposure depends on the number of towers nearby and how close they are.

Our RF sub-score measures exposure from towers within a 2-mile radius of your location, weighted by distance and tower type.

Why it matters: RF is the dominant source of EMF in most urban areas. The WHO classifies RF radiation as "possibly carcinogenic to humans," and multiple studies have shown effects on sleep quality and brain activity.

What is ELF?

ELF (extremely low frequency) fields are produced by power grid infrastructure: high-voltage transmission lines, substations, and transformers. ELF exposure drops quickly with distance but can be significant for homes near these structures.

Our ELF sub-score measures exposure from power infrastructure within 1 mile, weighted by voltage level and proximity.

Why it matters: Living near high-voltage power lines has been associated with increased health concerns in epidemiological studies. ELF exposure is often overlooked but can be a major factor for homes near substations or transmission corridors.
