Video receiver GEPRC MATEN 3.3G VRX with 3.3G Signal Alarmer

The GEPRC MATEN 3.3G VRX with 3.3G Alarm is a high-performance analog video receiver engineered for specialized long-range FPV operations within the alternative 3.3GHz frequency spectrum. Featuring an ultra-high sensitivity rating of -98dBm, this receiver guarantees exceptional signal acquisition and robust link stability over extreme distances. Housed inside a compact chassis equipped with a standard 1/4-inch threaded mounting hole, it integrates a smart signal analyzer with an audible tracking alarm system. Outfitted with a wide 12V to 36V voltage tolerance, it accommodates a comprehensive 40-channel matrix across 5 independent frequency bands and offers dual-mode operational flexibility with automated scanning logic.

Features

Specialized 3.3GHz Spectrum: Operates within the alternative 3.3GHz band, which inherently offers significantly better object penetration and lower atmospheric attenuation than standard 5.8GHz systems.

Ultra-High Sensitivity: Outfitted with a professional-grade -98dBm receiver core, maximizing video link retention and edge-of-range signal recovery during deep-range flights.

Audible Signal Tracking Alarm: Integrated hardware buzzer system provides real-time acoustic feedback during channel sweeps, increasing tone frequency as signal strength peaks.

Dual Operational Mode Core: Supports both a standard manual tuning profile (VRX Mode) and a fully automated spectrum analysis layout (Scan Mode).

Broad Voltage Compatibility Matrix: Supports a wide input voltage corridor from 12V to 36V DC, enabling hassle-free direct power integration straight from 3S to 8S LiPo battery mainlines.

Universal Mounting Layout: Built-in 1/4-inch threaded mounting socket ensures simple and secure tripod or ground station positioning hardware integration.

Operational Control Logic

VRX Mode: Standard operating mode for active flight tracking. Press the physical BAND button to cycle through frequency band groups (A through E). Press the physical CHAN button to shift between channel profiles (1 through 8). Press and hold either physical button to execute an automated background scan that locks onto the single strongest available localized RF signal.

SCAN Mode: Specialized diagnostic mode for spectrum verification. Switch to Scan Mode to initialize an automated sweep across all 40 available channels. The onboard processor will display the channel with the peak signal strength on the interface while triggering the acoustic alarm. The buzzer frequency scales up rapidly as the detected signal path strengthens, providing blind-tracking calibration assistance.

Notes

Before powering on the receiver ensure a high-quality 3.3GHz antenna is securely attached to the SMA terminal to prevent reception degradation or hardware component stress.

Operating transmission and reception hardware on the alternative 3.3GHz band requires specialized operator licensing and regulatory approval in most jurisdictions. Ensure your flight frequencies strictly comply with local RF allocations.
