**Advantages**：2dBi dual-frequency omnidirectional antenna, detection radius up to 2km, wide voltage low power consumption.

**Description**：Product functions: gaze direction finding for the detected target, scan the signal level of the UAV in 360° azimuth through manual operation, the unit quickly outputs the signal level of the frozen target, and finds the maximum direction as the direction

**Application Fields**：It is used for secondary development to build a general UAV detection system or equipment.

**High sensitivity**With a 2dBi dual-frequency omnidirectional antenna (60mm long, 15mm wide and 2mm thick, available), an omnidirectional detection radius of more than 2km can be achieved.

**Product advantage**All RF input ports are equipped with low loss limiter and can input continuous waves of up to 1W power without damage.

**Wide current low power consumption**In the input voltage range of 9~36V, the power consumption of the whole machine is less than 5w, and the 24V/5Ah battery can continue to work for more than 24 hours.

**Secondary development**According to the product design requirements, the detection unit is integrated, and the detection frequency band can cover 95% of the market UAV, and the performance advantage is more prominent.
