The Guardian3 BDA amplifies signals from the nearest radio tower to a building and from those radios back to the tower to compensate for weak reception caused by distance, topography, building structure etc. The BDA receives the signal from an outside antenna, amplifies that signal, and then rebroadcasts it via the interior antennas where it is picked up by radios. The interior antennas also pick up signals from radio devices and pass them to the BDA. The BDA amplifies these signals and passes them to the exterior antenna for rebroadcast back to the tower.
