Light weight Mini COFDM Transmitter Long Range 30km AV Sender for Quadcopter
Key Features:
Transmission distance is no less than 3 km under non-line-of-sight (NLOS) mobile transmission, ground to ground, with the height of both receiver and transmitter end being 3 meters;
No less than 30 km under ideal conditions, with slight non-synchronous electromagnetic interference;
And the maximum distance can reach over 100 km under clean electromagnetic environment.
Application:
This mini COFDM transmitter is mainly used by public security and security inspection departments for technical reconnaissance and evidence collection. Due to its extremely strong diffraction performance with a narrow bandwidth and excellent anti-interference capability, it is particularly suitable for wireless video transmission of low-altitude high-speed UAV drones and UGV equipment.
