Cell Tower Map & RF Exposure in Daly City, CA
Carriers Operating in Daly City
Daly City Nationally
Daly City's RF score of 55 falls in the middle range nationally, roughly in line with the typical US city.
5G in Daly City
Daly City has 206 active 5G towers, accounting for 18.9% of the local network. T-Mobile leads 5G deployment in the area. The network is still primarily 4G LTE, but as 5G expands, more neighborhoods will have higher-frequency antennas nearby. Searching your address shows which towers — including 5G — are closest to your home.
What Daly City's Tower Density Means for Residents
With 31.2/mi², Daly City has very dense tower coverage. Most residents live close to multiple towers, and scores range widely from 2 to 100. Checking your specific address is especially important — even moving a few blocks can make a meaningful difference.
Daly City's RF exposure is rated Elevated
Cell towers are the primary driver of EMF exposure in Daly City, 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 104,901 people, Daly City has a high concentration of wireless infrastructure — about 104.1 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 Daly City, CA
How Power Lines Affect Daly City Residents
Daly City has 23 transmission lines and 8 substations within 5 miles of the city center. The highest-voltage lines in the area carry up to 230 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 Daly City
There are 8 substations in the area, where high-voltage power is stepped down for local distribution. Like transmission lines, their ELF fields drop off quickly with distance. If you can see a substation from your home, it's worth checking your address to see how it affects your score.
Daly City's ELF exposure is rated Low
ELF isn't the main concern here — cell towers contribute far more to Daly City's overall EMF picture. Most residents are far enough from power infrastructure that it has minimal impact.
RF vs ELF in Daly City: Cell towers are the clear dominant factor in Daly City's EMF environment (RF: 55 vs ELF: 20). 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.
