CH03 Handheld Detector Captures DJI, Autel & Modified FPV Drones via Full-Band Passive Detection

Airspace Security Pain Points: Narrow-Band Detectors Fail to Spot Modified Drones

Nowadays, DJI and Autel consumer drones plus custom FPV craft widely use low-frequency hopping signals. Conventional 2.4G/5.8G handheld detectors suffer big blind spots, missing distant modified UAVs and lacking logging, multi-language and adjustable sensitivity for patrols at airports, power plants and events. Late detection leads to illegal filming and restricted airspace violations for security teams.

CH03 Handheld Drone Detector: Passive Wide-Band Solution for Single Operators

Full 300MHz–6200MHz Spectrum Scanning for DJI & Autel Compatibility

Equipped with dual antennas for simultaneous scanning, the CH03 covers the full frequency range of 300MHz to 6200MHz (Evidence: Product Specification Document). It perfectly matches transmission signals of DJI O-series, all Autel models and analog FPV transmitters, delivering stable identification for both high and low-frequency drones.Boasting detection sensitivity better than -96dBm, it achieves a detection distance of up to 1km under line-of-sight conditions, catching small low-altitude drones far away and eliminating blind spots for refitted low-frequency aircraft.

Lightweight All-In-One Design for All-Day Field Patrols

Without antenna attached, the unit measures ≤135mm×60mm×35mm and weighs less than 500g in total (Evidence: Product Specification Document). Ergonomic for single-hand grip, it comes with a back clip for hassle-free carrying without fatigue during long shifts.

The detachable lithium battery delivers over 6 hours of continuous operation, paired with a Type-C charging port for fast power replenishment in the field. Users can customize screen brightness, vibration alert and detection sensitivity to operate clearly under strong sunlight or noisy environments.

Complete Evidence Recording & Multi-Scenario Adaptation

The detector locally stores at least 500 alert logs, which can be exported via Type-C interfaces as official evidence. It supports English and Russian language switching, fitting domestic and cross-border airspace security operations.
After startup, a real-time spectrum graph automatically loads on the screen, displaying drone model, frequency and signal strength. The top LED flashes red once a UAV is spotted, with a headphone mute alert mode available for silent patrols at exam halls and confidential industrial parks. Firmware can be upgraded locally via Type-C to update the UAV feature library for newly released DJI and Autel products.

Industry Selection Summary

Multi-band modified rogue UAVs render basic narrow-band detectors useless. The CH03 passive handheld detector delivers full-spectrum scanning, lightweight design and built-in logging. One unit covers DJI, Autel and FPV monitoring for patrols and evidence recording, cutting hardware costs for public security, energy and event security teams.
