MULTI FUNCTION: This machine can detect 2G, 3G, 4G and wireless devices, 1.2G, 2.4G and 5.8G wireless cameras, and can accurately locate GPS. It can effectively prevent eavesdropping and secret photography, and help protect individual data and information confidentiality | ACCURATE 3 ALARM MODES: Simple to use, there are three alarm modes of sound vibration and LED indicator light, accurate and reliable. It can improve sensitivity, expand detection range, reduce sensitivity, shorten detection range, and identify radio wave sources faster and more accurately | RF DETECTOR: Ultra high sensitivity professional wireless detection device come with three antennas, used to detect RF 300‑700MHz, GSM 700‑2700MHz and 5.8GHz | WIDE APPLICATION: G618 can detect whether private addresses such as rooms, bedrooms, conference rooms, fitting rooms, hotel car entertainment venues are installed or mini cameras that can be secretly photographed, mini cameras with mobile phone card storage cards, mobile phone undercover software, GPS car locator | ADJUSTABLE SENSITIVITY: In a complex environment, can effectively filter the clutter of the signal, accurately get stable signal source for analysis, and adjust the sensitivity by pressing the button to determine the direction and distance of the signal source

MATERIAL: The PCB circuit board inside this filter module is exquisitely crafted, responsive, practical. | PASSBAND INSERTION LOSS: The filter can work in the range of 1 to 3000MHz, and the passband insertion loss is less than 1dB, which is very suitable for work use.z | STOPBAND SUPPRESSION: >50dB at 88-108M, anti FM interference. When the stopband rejection is greater than 50dB, the filter blocks the broadcast FM band between 88‑108MHz, with a stopband of 76MHz to 120MHz. | CONVENIENCE: This filter module is very small in size, compact in design, easy to carry, easy to install, and easy to operate. | MAIN FUNTION: This band stop filter can filter out FM, prevent the short from being affected by it, and ensure the purity of its wavelength.

SCOPE OF APPLICATION: It is only used to receive short-wave broadcasting, if there is a professional antenna, it can receive HAM communication. | NE602 HYBRID CHIP: HF upconverter adopts NE602 hybrid chip with stable performance. | HIGH-QUALITY MATERIALS: Inverter drives are made of high-quality materials, which are durable and have a long service life. | CONNECTING CABLE: HF upconverter has connecting cable to ensure the stability of the connection. | EASY TO USE: HF upconverter is easy to use and easy to operate.
