Frequently Asked Questions
Does your 10 watts/20 watts COFDM HD video transmitter support other frequencies, like 1.2G, 1.4G, 1.8G?
The transmitter frequency can be 160MHz~2700MHz, but our COFDM wireless receiver only supports 170~860MHz. For 1.2G, 1.4G, 1.8G, a frequency down converter is required at the receiver end.
Does this COFDM HD video transmitter support SDI video input?
Yes, We have COFDM wireless video transmitters support HDMI, SDI, CVBS AV, IP Ethernet RJ45 and AHD video input.
