AntennaSearch maps out cell tower locations.
The site is missing some towers. For instance, I do not see the local barn silo with a band of antennas around upper silo. Nor antennas on top of telephone poles along Darnestown Road nor Dufief Mill Road.
On the web site, you can click on the tower to see owner info. Map shows third parties own a lot of the towers.
Data gives the owner not which carriers use a tower.
The site can be slow and other times it is down.
The resultant images are:
Notice that there are a lot of single tower sites in blue. Red are multiple.
