Q: Can you change this product’s working frequency to 2.7GHz?
A: да, the working frequency is customized. The COFDM HDMI video transmitted frequency range covers 300MHz-3500MHz (3.5GHz), so it also supports 2.7GHz 2700MHz. But COFDM HDMI wireless receiver frequency only supports 170~860MHz. If you need 2.7G, you should use a frequency down converter at the receiver side. https://ivcan.com/p/cofdm-rf-frequency-down-converter/ extra cost increase USD790.
Q: Can you make it as a two-way transmission or one-way transmission？
A: This depends on the actual needs of your project. Our two-way transmission system not only downloads the video from the drone to the ground receiving station but also sends the control signal or command from the ground receiving station to the drone in the air at the same time. The one-way transmission system only completes the real-time download of the video from the drone, and cannot send control commands in the reverse direction.
2.7GHz и двупосочна video data transmission system, we recommended the below link.
VTX for drone video data link long-range transmitter-receiver 30-50km 2X1.6WPA
One unit costs USD1450, if you need one transmitter and one receiver, one pair costs USD1450x2=USD2900.
Please note that two-way transmission mostly uses Ethernet LAN IP RJ45 as a video input connector, so if you want to use it for an HDMI camera, then you also need one HDMI to IP video encoder, which will have an extra cost of USD399.
2.7GHz и еднопосочен video data transmission system, we recommended the below link.
