COFDM Wireless Downlink Receiver

The COFDM Diversity Receiver is compact digital diversity receiver with integrated H.264 or H.265 decoding in a compact and lightweight housing, suitable for use in fluid and high-mobility applications. The unit accepts signals from two antennas to significantly enhance the demodulated performance and increase the operating range. The receiver can find and lock automatically to the incoming transmission quickly according to the pre-set frequency and bandwidth. This receiver features a range of comprehensive signal outputs including HD at 720p and 1080P, down-converted HD CVBS monitor video, and two analog audios is supported.
The receiver also includes DVR record functionality with Micro SD card or USB disk using REC switch controls. When paired with the COFDM wireless Downlink camera transmitter, the receiver offers a comprehensive, rapidly-deployable video and audio solution that enables advanced situational awareness. It can play an essential role in delivering real-time live video from both ground and airborne mobile platforms.

• COFDM demodulation and H.264 or H.265 video decoder;
• Full HD resolution, 1080P@60fps;
• Great security by AES decryption;
• Modular design and highly integrated;
• Stable signal transfer in NLOS and high speed moving.
• Adjustable working frequency, band width.
