Wireless video transmitters and receivers for go-karts

Kamusta, I am from a video production company.
Now we are researching whether a set of wireless image transmissions can be installed on the go-kart (tentatively 20 sets).
Are there any solutions that can be provided?
Half LOS, estimated straight-line distance is 2KM, video output SDI/HDMI would be more convenient if NDI is available.

Does your COFDM transmitter support our diversity receiver? I need AES encryption and SDI input.
