170MHz - 2900MHz RF COFDM Modulator Video Transmitter For Drone Analog Video Link
Key Features:
Transmission distance:
In non-line-of-sight (NLOS) mobile transmission, ground to ground, with the height of both receiver and transmitter end are both 3 meters, the transmission distance is at least 3km;
Under ideal conditions, with slight non-synchronous electromagnetic interference;transmission range is at least 30 km;
In a clean electromagnetic environment, the maximum transmission distance can reach over 100 km.
Application:
This COFDM modulator video transmitter is mainly applied in technical reconnaissance and evidence collection by the public security and security inspection departments. Due to its extremely strong diffraction performance and high anti-interference ability in narrow bandwidth, it is particularly suitable for wireless video transmission of low-altitude high-speed UAV drones and UGV equipment.
