Second time
So I’ll be honest I bought this a few years back no clue it’s purpose. Now just bought one to do Go with firebox. I hooked up my mom’s box at Christmas and it’s in a closet. Yes I know not supposed to be in the closet but long story . That is where it is. So this extender device works. I still don’t really understand the purpose but we got the kitchen tv working yay!
