5G in Annapolis

Annapolis has 106 active 5G towers, accounting for 23.9% 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 Annapolis's Tower Density Means for Residents

With 21.8/mi², Annapolis has dense tower coverage. Many residents have at least one tower within a few blocks, but EMF scores still range widely — from 2 to 100. Even in a dense tower environment, your exact location relative to tower clusters makes a significant difference.

Annapolis's RF exposure is rated Moderate

The city average is moderate, but scores range from 2 to 100 — your neighborhood makes a real difference. Search your address to see where you fall.

What This Means for You

RF exposure from cell towers drops sharply with distance. In Annapolis, scores range from 2 to 100, which means your specific location matters more than the city average. Search your address to see what's nearby — especially which direction towers are from your bedrooms.

Power Lines & ELF Exposure in Annapolis, MD

100–229 kV

How Power Lines Affect Annapolis Residents

Annapolis has 8 transmission lines and 9 substations within 5 miles of the city center. The area has more substations than transmission lines, which is common in distribution-heavy zones. Substations generate localized ELF fields that drop off quickly — typically within a few hundred meters. If you can see one from your home, checking your address will show how it affects your score.

Substations Near Annapolis

There are 9 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.

Annapolis's ELF exposure is rated Very Low

ELF isn't the main concern here — cell towers contribute far more to Annapolis's overall EMF picture. Most residents are far enough from power infrastructure that it has minimal impact.

RF vs ELF in Annapolis: Cell towers are the clear dominant factor in Annapolis's EMF environment (RF: 36 vs ELF: 10). 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.
