Frequently Asked Questions
Q1. Does your 10 watts/20 watts COFDM HD video transmitter support other frequencies, like 1.2G,1.4G, 1.8G?
A: 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.
Q2. Does this COFDM HD video transmitter support SDI video input?
A: Yes, We have COFDM wireless video transmitters support HDMI, SDI, CVBS AV, IP Ethernet RJ45 and AHD video input.
