I want to install coaxial wall outlets throughout my home. The only ones I was able to find are these two-way outlets, with a male and a female connector. What I find confusing is that the outlet also has two places where you can insert the cable, one with an arrow pointing down (away, like an output) and another pointing up (inwards, like an input).

So my questions are:

  • Why are there both male and female connectors?
  • Why are there two places to insert the coaxial cable? What do the in/up and out/down arrows represent, and when would you use either?
  • I use this cable for internet and TV connections. Should I use the in/up connection?
  • Will both the male and female connectors work simultaneously? Can I have a TV and a router connected to the same wall outlet?

The coaxial wall outlet I purchased

  • The in/up is from the cable company, the out/down is to tv.

  • Can you please clarify? What do you mean to TV? Commented Mar 21 at 22:40
  • The out port goes to something in the house. TV was probably bad wording on my part, probably goes to a router first.

  • Not a style of coaxial connector I recognize...

    Where in the world do you live? That looks nothing like the standard TV/Internet coax jack found in the USA.

Instead of that thing (?) you have, use a simple wall mount F barrel connector, no box needed. Use quad-shielded RG6 coax cable cut to length and attach male F connectors to each end. You will need to design the distribution system (splitters, possibly bidirectional amplifiers for cable boxes, etc.). If you're wanting to run data lines from your cable modem, you would use UTP instead of coax, changing everything.

  • My internet subscription comes over coax, which goes into the modem, which then goes to the router. Thank you for the effort, but your answer is not useful to me since it applies to a different situation than what I described. Maybe it'll help someone else. Commented Mar 27 at 18:04
  • Could you provide more info, perhaps in a sketch showing incoming coax, modem, router, tv’s, data and tv jacks.. pic of backside of that device you’re asking about, and any info about it. What country? (Connectors in pic nonstandard in US.). Are tv and data coming in on single coax to a splitter that feeds modem and several TV outlets? Smart TVs? Are you wanting to use coax jacks for data?
