sorry I havent been able to put the pics up any sooner, but I will tonight. As far as making something so they plug into each other, I doubt it, because the cables are coaxial, and are "tuned to certain frequencies" by how long it is. I don't know how true that is, the instructions for the antenna tell you not to alter the length of the cable. I really wouldnt put the antenna anywhere else inside the car, other than on the dash, but that would probably look ugly. Like I said though, I'll take pics of mine so you can see what I was talking about.
Hope all this info helps!
