Hi, seen a video ages ago showing how to mod a PS4 to attach an external antenna. Have finally decided to do it and have found all of the parts I need on Amazon but I am stuck with something and need some advice.

My PS4 is located in a hallway closet along with all my other A/V & networking gear and I am wanting to connect an antenna to pick up my controller signal from my bedroom roughly 15m away. I was planning on running a cable from the PS4 through the roof and having the antenna sitting right above my bedroom where I will be sitting, however this is not the primary location I play from. If I take the signal to an antenna at the other end of the house I will not be able to play from my living room (where I do 90% of my gaming) which is roughly 5m in the opposite direction. I am thinking that I need something like a 1 into 2 splitter so I can wire 2 antenna through the roof and have them above both areas.

Here lies the problem - the splitter.

I have little experience with RF cables and antenna, I was thinking a T adaptor would do the trick but after a searching the web I'm not so sure it will work because of impodences and/or signal loss. The search results were returning information mainly for extending wifi signals because from what I understand the same cable is used for both applications. People talk about signal losses and impodence mix matching (stuff I don't really understand) but I was wondering if that would have any real effect on what I am trying to achieve with gaining bluetooth range. I found that there are power adaptors but they look to be quite expensive and don't know if I need one.

The antenna I am looking at getting: Super Power Supply 2 x 12dBi 2.4Ghz 5Ghz Dual Band WiFi RP-SMA Antenna
