Fixed Wing Drone Video Data Link

I came across your video and data link and was interested to know more.
We use fixed wing drones and were looking for a solution for 60 + kms data and video link
We have an AYK 250 drone
We have been using the VD PRO 60 skakel. We wanted to update our drone.
With this, I will get 60km real-time data?
Which frequency would you recommend for us to use? Is 1.4GHz frequency good enough?
Can you just confirm the power supply for this? We have a 24V 2A power supply – that is enough? It should use 24 3A.
