The transmitter frequency can be 160MHz~2700MHz, but our COFDM wireless receiver only supports 170~860MHz. For 1.2G or 1.4G, a frequency down converter is required at the receiver end.

Yes, our COFDM HD transmitters support HDMI, SDI, CVBS AV, IP Ethernet RJ45 and AHD video input. Please specify your preferred video type.

For UAV applications, the transmission range is about 50km when the UAV is at 300 meters altitude with receiver antennas positioned as high as possible.

Yes, it supports three working modes: standard DVB-T protocol, COFDM protocol with encryption/decryption, and COFDM low latency protocol with H264 encoding.

Our transmitters support one HDMI and one auxiliary CVBS audio/video input simultaneously. Currently, only one sound source is supported (selectable between HDMI or CVBS via parameter configuration).
