WATS
Single-module, wideband analog video transmission system. Transmits and receives analog video across any frequency from 100 MHz to 6650 MHz. Flexible solution for building analog video links without fixed-frequency-band limits.
Overview
Supports standard PAL and NTSC analog video formats. Compact single-module design, wide tuning range, Western components supply chain.
Transmitter
- Supports analog video transmission through three selectable RF output ports
- Each port can be configured and matched with external power amplifiers for specific applications
- Integrated analog video sync signal analyzer detects incoming video frames from the camera
- Can enable frequency-hopping operation, providing high resilience to EMI interference and intentional jamming
Receiver
- High-sensitivity receiver across the full 100–6650 MHz range, receives and decodes incoming analog video
- Integrated high-sensitivity RSSI measurement system can operate as a standalone wideband signal scanner / basic spectrum monitoring tool without video decoding
- Decoded video output directly in PAL/NTSC to any compatible analog display
- Integrated video frame sync detector enables precise frame detection and frequency-hopping operation

Applications
Generic Video Transmission with Frequency Hopping
The transmitter and receiver modules can form a flexible analog video link operating anywhere between 100 MHz and 6650 MHz. Integrated video frame synchronization detection enables frame-aligned frequency hopping, allowing the system to dynamically change frequencies and maintain reliable transmission in environments with high interference or jamming.
Wideband Monitoring and Drone Video Interception
The receiver’s high-sensitivity RSSI measurement system enables wideband RF monitoring across the full operating spectrum. Detected analog video transmissions can be quickly tuned and decoded, allowing interception of analog video feeds for monitoring or situational awareness applications.
Drone Direction Detection and Video Interception
Using RSSI measurements and directional antennas, the receiver can help estimate the direction of incoming video transmissions. Once detected, the system can tune to the signal frequency and decode the drone’s video stream, enabling both signal tracking and video observation.
RF Spectrum Mapping and Heatmap Generation
By collecting RSSI measurements across different frequencies and locations, the receiver can be used to generate RF activity heatmaps. This allows identification of active transmitters, frequently used spectrum bands, and potential interference sources.
Wideband Video Retransmission Systems
The system can be used to receive analog video on one frequency and retransmit it on another, including non-standard frequency bands. This enables flexible retransmission, frequency conversion, and integration between otherwise incompatible analog video systems.
