I used this before to hook up a video game console to a TV without digital channels. If the cable box has that yellow jack, you can connect it to the yellow part of the this converter, and then connect the regular TV cable to from the box to the TV.
I believe so. I just know that when my ex-husband wanted to hook up his x-box, I went to radio shack and told them my situation... so this is what they gave to me and it worked. Needless to say the ex-husband the x-box are gone, but the RF modulator remains. LOL
I'll get a pic in the morning, somebody's sleeping in the "stock room" It's kinda boring in the front, it just has a small "on" indicator light that only comes on when you've actually got everything connected right, and in small white letters it says Radio Shack.
