Frequently Asked Questions:
Q1. Does your COFDM transmitter support changing frequency?
A:The transmitter frequency can be 160MHz~2700MHz, but our COFDM wireless receiver only supports 170~860MHz. You can specifie a center frequency point, then our RF power amplifier will normally be made to operate within a frequency range of center frequency ±15 MHz .
By the way, if you want frequency 860MHz~2700MHz, need to intall a frequency down converter at the receiver end.
Q2. Does this COFDM transmitter support SDI video input?
A: Yes, our COFDM transmitter supports HDMI, SDI, CVBS AV, IP Ethernet RJ45 and AHD video input, please just let us know what video input you want.
Q3. What's the max distance for the COFDM transmitter with 2.5W PA power amplifier?
A: For UAV/ Drone application, the LOS transmission range is about 50km, the height of UAV is about 300 meters, and install the antennas of receiver as high as possible.
Q4. Does your VTX and RX support standard DVB-T protocol?
A: Yes, it supports 3 working modes:
- Standard DVB-T protocol, normal DVB-T can get the transmitter signal, no encryption and decrryption functions.
- COFDM protocol, support TX encryption and RX decryption, support H265 and H264 encoding, but no super low latency mode.
- COFDM low latency protocol, H264 encoding with low latency, support TX encryption and RX decryption function.
Q5.I want a set of COFDM transmitter and receiver to transmit 2 channels video simultaneously, one HDMI video and one audio, can it work?
A: Our weireless COFDM transmitter support one HDMI and one auxiliary CVBS audio and video input at the same time. Currently, it can only support one sound source, which can be modified by our parameter configuration board, to choose HDMI sound or CVBS sound.
