Product Description
Lightweight Mini COFDM Transmitter - Long Range 30km AV Sender for Quadcopter
| Modulation | COFDM |
| Working voltage | DC11V~DC18V |
| Video encoding format | H.265 |
| Input video | Standard resolution analog video signal |
| Place of Origin | Guangdong, China |
| OEM & ODM | Supported |
Key Features:
- Mini size, lightweight, modular and combined design
- Combines COFDM modulation with H.265 encoding technology
- Simultaneously transmits one analog video signal and one unidirectional data (up to 230400 bps)
- Low latency with end-to-end latency as low as 120ms
- Excellent diffraction performance for comprehensive communication
- Supports NLOS (Non-Line-of-Sight) and high-speed mobile transmission
- Aluminum case for heat dissipation, shock resistance, and impact resistance
- Transmission distance ≥3km (NLOS mobile transmission, ground-to-ground, 3m height)
- Transmission distance ≥30km (ideal conditions with slight interference)
- Maximum distance can exceed 100km in clean electromagnetic environments
- Supports moving speeds up to 600 km/h
- Fully customizable solutions available
Applications:
This mini COFDM transmitter is primarily used by public security and security inspection departments for technical reconnaissance and evidence collection. Its strong diffraction performance with narrow bandwidth and excellent anti-interference capability makes it particularly suitable for wireless video transmission in low-altitude high-speed UAV drones and UGV equipment.
