30Km long distance COFDM HDMI Wireless Video Transmitter

FAQ

Question 1: I need at least a 30km range from air to ground for the UAV UGV USV.

Answer 1：Our system supports it, it should use a 2W power amplifier, it is better to use the special long transmitter antenna and two higher receiver antennas.

COFDM-912T VS COFDM-908T

Question 2: How far can I get if I use the transmitter and receiver both on the ground?

Answer: On ground use, the transmitter and receiver must have a certain height difference to transmit long distances.

The longest distance is only 2.5 kilometers if the transmitter and receiver are both at the same height on the ground. Please see our test video; because the transmitter and receiver are placed at different levels, one side is at the mountain, another side is at the seaside, we used the default two watts to transmit 27 kilometers.

Question 3: Does it support a working environment of -20 degrees?

Answer: Yes, supported
