Mounting 2014 Mistral TV in Volvo FH500: Active DVB-T Antenna & Preserving Warranty

Hello, I am to mount a TV year 2014 in Volvo FH truck, Mistral TV sets are installed in Volvo services. These TV's are at 12V and you can get them without any problem. And so after a video on youtu .. (https://www.youtube.com/watch?v=SPX3DKbDrqA) I learned that these TVs for Volvo are specially converted from the antenna input. The case looks like that the factory antenna installation of this vehicle has an active DVB-t antenna already supplied with 5V voltage and the point is to separate this voltage from the TV.
How can this be done without TV conversion so as not to lose the warranty? Some separating filter?

The topic resolved, it turned out that there is no power supply to the antenna and the TV sets are converted to give them, I made a 5V separator powered by USB.
Thanks for the hints.
