Where are the mobile phone antennas?

The Ministry of Industry, Energy and Tourism has a web page with an application that allows you to visualize the location of the different cell phone antennas, both for the 2G network and for UMTS or 3G

If we click on the link framed in red, the following web page opens:

To see the location of mobile telephony antennas, simply select a province and a municipality, or zoom in directly on the map until you reach the desired area

To see the location of the antennas, indicated by a purple circle, simply zoom in by clicking on the desired area. If we also select "aerial image" then we will see on a Google maps map the location of the cell phone antennas.

If we click with the mouse on each of the blue dots we will see the characteristics and the operator owner of each of the cell phone antennas.
