re: Want to put cable box in closet (cox)

that one linked is also on amazon for the same price i believe. that's the monoprice.. which is usually a great brand but the reviews are hit and miss

this one has good reviews and should work the same. check the feedback for it, there is an actual video review you can watch as well.

this is the monoprice

they just seem like hit and miss. works great for some, not for others. just keep doing your research and maybe buy from someone you know you can return easily if needed. hope you figure it out.

Watch this video for a tutorial! LINK
that model version has been discontinued.. but the other links have the newer version i believe.. that should give you an idea how they work though.
