RF Explorer has been designed for signal booster system installers to detect signal distance, strength and direction when installing and troubleshooting wireless systems e.g. weBoost, SureCall, HiBoost, and Wilson Pro signal booster systems by Wilson Electronics.

This unit has been designed to be intuitive and easy to use without having to read complicated manuals to understand its advanced functionality. Most of the intricacy typically found in full sized Spectrum Analyzers has been simplified with functionality that is automatically resolved by the firmware. Based on an integrated double balanced mixer and frequency synthesizer, the unit offers compact size, high performance and low consumption, all at a low cost.

Two SMA connectors are provided for the two antennas included - a whip helical for the 2.4 GHz band and a wide-band telescopic antenna for Sub-GHz frequencies.

Accessories included.

  • 1 × RF Explorer signal meter.
  • 1 × Helical whip antenna for frequencies above 1000 MHz.
  • 1 × Wideband telescoping antenna (Nagoya NA-773) for frequencies below 1000 MHz.
  • 1 × hard-sided case (black).


Sorry, we have had too many instances of returns after use when no longer needed. Therefore, units that are operating as intended may not be returned for refund. Faulty units will only be exchanged under manufacturers warranty. Sorry, we do not rent this RF signal detector, it must be purchased outright.

Questions & Answers


Ask a Question
  • I'm looking for a device to tell me the strength of signal for the area of installation of radio remote read card inside of electric meters. Will this device help me with that?

    Yes, this should be the right model for your needs. To double check, please let us know the exact frequency range the electric meter remote connections work on.

  • I fly radio-controlled airplanes utilizing the 2.4 Ghz band. These systems are supposed to be bulletproof as they implement frequency-hopping technology. Alas, myself and several of my compatriots have had "hits" resulting in loss of control and crashes. We suspect there is some intermittent source of interfering RF energy, perhaps miles away from our flying site, that is either interfering with or "washing out" our radio-control systems even though it is claimed to be IMPOSSIBLE to do so. Would this device be able to detect such (potentially low-powered) sources in thh 2.4 Ghz band??

    While the signal meter may detect the signal strength in that frequency, there is no way to determine the source of the signal.

  • I'm looking for a device that can detect various television broadcast over-the-air signals and determine the strength of those signals. Is this a product that can do that and if so, can i assume that you do not need to be connected to any other device/anetenna and that it is portable and can detect if there is a signal anywhere outside, correct?

    Since that signal meter covers frequencies most TV transmissions start at, it should help you. Antenna that comes with the meter would be sufficient.
