A: 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.
A: Yes, our COFDM wireless video transmitters support HDMI, SDI, CVBS AV, IP Ethernet RJ45 and AHD video input.
A: For UAV applications, the transmission range is about 100km when the UAV is at approximately 500 meters altitude with receiver antennas positioned as high as possible.
A: Yes, it supports three working modes:
1. Standard DVB-T protocol (no encryption)
2. COFDM protocol with encryption/decryption (H265/H264 encoding)
3. COFDM low latency protocol (H264 encoding with encryption/decryption)
A: Our COFDM wireless transmitters support one HDMI and one auxiliary CVBS audio/video input simultaneously. Currently, only one sound source is supported, selectable between HDMI or CVBS sound via our parameter configuration board.
