What adapter do I need to connect indoor antennas to digital converter boxes?

Question

I have bought two boxes of different brands and a Phillips and RCA antenna. Neither of the antenna cables will connect to the Antenna IN on the boxes because they are the same diameter and just butt together, but won't connect!

Answer 1

You have a "coupler" inside the end of your antenna wire. Unscrew the coupler from your antenna wire, then attach the antenna wire onto the digital box. :o)

(a coupler is used to connect two cables together. it's about 1" long. If you have a coupler screwed into your cable coming from your antenna, the connectors between your cable and your new digital box will be exactly the same, and will not s***w together, which is the symptom you are having)
