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. Relationship Between Transmission Distance and Height Technical Specifications: | Model No. | HC-S5 | | Modulation | COFDM | | Working voltage | DC11V~DC18V | | Working current | Mainboard current: 160mA
