Frequently Asked Questions
Q1. Does your 10 watts/20 watts COFDM Wireless video transmitter support changing frequency to be 1.2G/1.4G?
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.
Q2. Does this COFDM wireless video transmitter support SDI video input?
A: Yes, our COFDM wireless video transmitters support HDMI, SDI, CVBS AV, IP Ethernet RJ45 and AHD video input.
Q3. What's the max distance for the 10W PA transmitter?
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.
