I was wondering if your enquiry was as a result of a post I saw you made
here where you said your video signal was failing to start or dropping in and out for no apparent reason. If it is, then you need to find the root cause of the lack of video feed as fitting a booster is very unlikely to sort it out.
But in any case, before this can move forward any further you need to positively and definitely identify which model of P3 you have.
With all due respect, I also think that you will need to have a much greater understanding of the technology and type of work involved and the skills needed before undertaking such a project.
