Divert power to the rf input

[magedrifaat]

Hello everybody,
I apologize in advance if this question is very stupid or very off-topic as I am very new to all of this but you seem to be the experts so it looks like the right place to ask.
I have an active antenna that requires 5 volts DC on the coaxial cable to work. I know power inserters are a thing but apparently no one else knows about them around here and they are rare anywhere else anyways. My question is, Is there a way or an option to divert power (ideally 5 volts) to the RF output of the TV? Maybe an option hidden in the service menu?
I have a digital tuner box that does that so I wonder if the TV can too.
My TV model is: PA43H400ARXEG.
