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 includes an antenna or 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). Easy-to-use button controls located just under the screen allow the user to move between frequency bands and channels. This device works with the 800 MHz (Cellular), 1900 MHz (PCS), 2100 MHz (AWS) and 700 MHz LTE (bands 12 and 13) frequency bands. The RF Signal Detector is the perfect tool to help you optimize a Wilson signal booster installation or tune a directional antenna.

The purpose of the RF Signal Detector is to assist the installation of a Wilson Electronics Signal Booster, specifically for:

  • Mapping the frequency environment
  • Aiming directional antennas
  • Maximizing Wilson® Electronics Signal Booster coverage


  • Detects and displays available signal frequency, bandwidth and strength
  • Works with 700, 800, 1900 and 2100 (AWS) MHz spectrum bands
  • Configurable with a variety of Wilson antennas
  • Detects available signal indoors or outdoors
  • Switches easily between frequency bands and channels
  • Antenna included (or you can provide your own antenna)
  • Includes a battery pack (requires 8 AA batteries, not included); signal tester can operate for approximately 4-6 hours on battery power

Installer Benefits:

  • Determine which cellular signals, including 3G & 4G, are available for any location
  • Find the strongest available signal
