We have a piece of RG6 Quad in one area of a building and we can't seem to find the other end of it. I thought that I knew where it went as I installe d all these cables, but it's just not there. I have a small tone generator and an inductive probe that work well on unshielded wire, but attempts at u sing this on shielded cable have always been a problem. I've been thinking of trying to set my old HP200CD audio oscillator to 1KHZ and really crank i t up and feed it into the cable. The 200CD will output a respectable signal across 600 ohms, (naturally I'd be using it unterminated here), and I wond er if I'd be able to pick it up through the cable then?
The only other thing I can think of,(and this is probably not very practica l) is to inject a high enough RF frequency into the cable at a level where it would egress. Perhaps I might be able to see this on my spectrum analyze r. Of course I realize that the superior shielding of the quad cable is wor king against me here too.
I know that there must be equipment designed to do this, but I'm not really in a position to make a purchase like that. Does anyone have any suggestio ns for finding this cable? Thanks, Lenny
