The RF Signal Detector from Wilson Electronics is a quad-band detector that finds the available cellular signals in any location and displays signal attributes on the detector’s LCD screen. This signal detector can be paired with a variety of Wilson antennas to map the local cellular frequency environment and find the direction of the cell tower that provides the strongest signal. This allows you to precisely point a directional antenna so a Wilson signal booster can maximize indoor cellular coverage. The Signal Detector’s LCD screen displays the frequency of a detected signal, the range of pass bandwidth in megahertz (MHz) and the signal strength in decibels (dB).
