There are an estimated 1.3 million base station antennas installed on towers and rooftops worldwide. As more and more of these are installed to increase coverage and to power new applications the ocean of electropollution to which we are exposed will only continue to thicken. Cell towers and antennas are popping up everywhere. In the United States there are now more than 1,947,000 towers and antennas currently online. Towers are the structures on which antennas are placed and multiple antennas may be attached to a single tower. The antenna is the actual emitter of the radio signal. Antennas are placed not only on towers but also on fires stations, churches, schools, cemeteries, and even in
our national parks. Did you know there’s a cell tower near Old Faithful in Yellowstone Park? And to make them esthetically pleasing to the environment antenna towers are often disguised. It’s not uncommon to see cell phone towers in the southwest that look like palm trees, for example. These towers and antennas are often hidden, too, in places like church steeples or placed on rooftops where they can’t be seen. Can’t sleep well in a hotel at night? There may be an antenna tower hidden on the roof. As explained earlier, each cell phone tower emits its signal in a circular pattern that would look much like a flower petal if it were visible. In other words, the pattern spreads itself 360 degrees around the tower in a circle. This “circle” around the tower is called a “cell” and this is where the term “cell” in cell phone gets its name. When under the umbrella of the “cell” good reception is maintained. When out of this cell area the reception is poor. Cell phone towers, then, are positioned throughout the countryside in such a way that these “cells” overlap one another so that, ideally, one is never out of coverage anywhere.
