Ever wonder how close one is to a cell tower? With http://www.antennasearch.com/ you can find out.
I was having trouble with my provider and I wanted to know how close I was to my provider's towers. Pop in a United States based address and soon enough, the results will map out where the towers are and if there are any permits on file for new tower construction.
As for my results, I'm in a small deadzone.
