Feature:1. Wide Coverage Area: RF signal detector with wideband antenna (for ant1 socket), wider coverage, especially at lower frequencies, allows to increase the detection distance of traditional vhf uhf bug, while saving perfect sensitivity in higher frequency bands (gsm, wifi, Bluetooth, etc.).2. Directional Antenna: The bug detector has an antenna (for ant2 socket) to obtain the microwave log periodic directional antenna provided in the standard kit. Extends the distance 24 times with all sources above 2ghz (wifi 2.4ghz, wifi 5ghz, Bluetooth, for wi max, for Ite high, etc.).3. Magnetic Field Signal Detection: Listening device detector uses magnetic field signal detection, install the magnetic probe, turn on the power, press the strong magnetic detection switch, the purple indicator light on the top will enter the detection standby state, once the magnetic field sensing probe is close to the magnetic field source, it will light up in the terminal white LED and buzzer alarm.4. Superior Performance: RF signal detector has high sensitivity, ultra high anti interference, farther detection range, wider detection frequency range, covering a variety of devices. Directionality can easily locate wireless sources, fast detection, and can find WiFi sources.5. Wide Scenes, Full Kit: Bug detector is suitable for public bathrooms, hotels, vacation rentals, locker rooms, recreation rooms, locker rooms, business meetings and school exams. Kit includes 1 x signal detector, 2 x antennas, 1 x USB cable, 1 x accessory, 1 x instruction manual.Specification:Item Type: RF Signal DetectorMaterial: ABS, Aluminum AlloyWeight: Approx. 392g/13.8ozSize: Approx. 13.7x2.3x7.5cm / 5.4x0.9x3.0in Frequency Range: 50MHz-5.4GHzDetection Dynamic Range: -50dBm-10dBmDetection Sensitivity: <0.03mw (Main Frequency)Detection Range: 2.4GHzMobile Phone Signal 2G, 3G, 4G: 5-25 mMagnetic Detection Sensitivity: 50mm-150mmIndication Method: 20 Level LED Illuminated Indicator, Change Sound IndicationPower Supply: Built in 3.7V, 1500mAh, Lithium Polymer Battery (with Built in Battery Shipped)Working Current: 25-35mAUsage: Signal Detector.Package List:1 xRF Signal Detector2 x Antenna1 x USB Cable1 x Accessories1 x ManualNote:Please allow some error in manual measurement.
