I always question the accuracy of these tower locations.These apps show a couple tower locations around my house.
I have gone to those locations and found no cell towers or antennas.
A tower close to my house that I thought was a Verizon Tower (Since it says Ameritech on a sign) is never shown as a Verizon location.
I'm not sure where this info comes from, but it doesn't seem very accurate.
I'm not saying the app is not accurate. I think the database where this tower location information comes from maybe incorrect.
