Cell Tower Map & RF Exposure in Pomona, CA
Carriers Operating in Pomona
Pomona Nationally
Pomona's RF score of 63 puts it in the bottom quarter nationally — lower cell tower exposure than roughly 75% of US cities we track.
5G in Pomona
Pomona has just 43 5G towers so far — a small fraction of the network. Most wireless coverage relies on 4G LTE and older technologies. As carriers like T-Mobile continue rolling out 5G, this will change, potentially shifting RF exposure patterns in the area.
What Pomona's Tower Density Means for Residents
With 22.9/mi², Pomona has dense tower coverage. Many residents have at least one tower within a few blocks, but EMF scores still range widely — from 35 to 100. Even in a dense tower environment, your exact location relative to tower clusters makes a significant difference.
Pomona's RF exposure is rated Elevated
Cell towers are the primary driver of EMF exposure in Pomona, and many residents have elevated RF from nearby infrastructure. Search your address to see how your specific location compares.
What This Means for You
For a city of 147,966 people, Pomona has a high concentration of wireless infrastructure — about 35.5 towers per 10,000 residents. Your personal exposure depends on how close towers are to your home, especially to bedrooms. Search your address to see exactly which towers affect you.
Power Lines & ELF Exposure in Pomona, CA
How Power Lines Affect Pomona Residents
Pomona has 34 transmission lines and 28 substations within 5 miles of the city center. The highest-voltage lines in the area carry up to 287 kV. ELF fields drop off sharply with distance — most homes beyond 300-500 meters from a transmission line see very low exposure. But for homes closer than that, especially near higher-voltage corridors, the impact can be significant.
Substations Near Pomona
With 28 substations in the area, Pomona has significant power distribution infrastructure. These are the points where high-voltage power is stepped down for local use. Each one creates a localized ELF field — if you live within a few hundred meters of one, it likely contributes to your score. The map shows exactly where they are.
Pomona's ELF exposure is rated Moderate
Some parts of the city are close to power grid infrastructure. If you live near visible power lines or a substation, checking your address will show how much they contribute to your personal EMF score.
RF vs ELF in Pomona: Cell towers are the clear dominant factor in Pomona's EMF environment (RF: 63 vs ELF: 38). Choosing a home away from tower clusters will have the biggest effect on reducing your overall exposure.
What This Means for You
Unlike cell tower RF, which is spread across many towers, ELF exposure is very location-specific. You could live a few blocks from a power line and barely notice it in your score, or live right next to one and see a significant impact. Check your address to see if any are close enough to affect your home.
How Pomona Compares: Cell Towers & EMF Scores
Pomona's EMF exposure level of 63 is notably higher than both the California state average of 46 and the national median of 45, placing it in the elevated risk category. While not the highest in California—cities like Temecula and Murrieta have lower exposure scores—Pomona residents may want to consider additional electromagnetic field mitigation strategies or explore lower-exposure neighborhoods within the region.

Studies have found measurable effects on sleep quality from RF-EMF exposure, though effect sizes vary.
Some researchers recommend lower limits for children, citing developing nervous systems and longer lifetime exposure.
Many choose to minimize exposure based on the precautionary principle: when science is uncertain but consequences may be significant, reducing exposure is reasonable.
