testing continuity of coax cable
Previous homeowner had 3 coax cables going thru a conduit and didn't label the cables. I'd like to label each end so I know which cable is which on both ends. I do not currently have a satellite signal, but I could hook the cables up to a receiver to generate a "current", then test the other end. How do I do this? Do I need a signal meter? A test light? Thoughts? Thanks.

You can use a Barrel connector and a 75 ohm terminator cap-Connect the barrel to one end and then screw the terminator onto the barrel- with a Volt-ohm meter set to ohms-test the other end's of the RG6 when you find the one that reads 75 ohms (mark it) and the move the barrel to the next wire and so on.

If you hook one end to a receiver, then you would use a Volt-Ohm meter to check for voltage on the other end. One lead will touch the side of the connector, while the other lead will touch the copper semi-conductor.

sure fire easy way without any tools is hook up one of your receivers at the location and turn it on. Then go to where the cable ends in question are and give each cable end a light touch to the tip of your tounge. If you feel a bitterness/tingle much like putting your tounge on a 9v battery that's the line your looking for. I would recommend either of the aforementioned methods over this of course but if you are in a hurry and don't have or don't want to buy such tools for a one time usage this will get ya what you're looking for.

I def recommend this tongue in cable method for those who need to find a cable and don't have the necessary tools.

With only three cables the healing time for the tongue shouldn't exceed 10 days or so.

Thanks to those of you that responded; your help was invaluable. I have a volt / ohm meter, so I went that route first, but I blew the fuse in the meter because I had it set at too low a scale, so I had to revert to the tongue method. Let me just say, I'm pretty sure a DirecTV circuit is greater than a 9-volt battery. Yikes! I should've let my 13-year old grandson test it for me!

lol. actually the receiver outputs anywhere from 13v to 18v. Enough to give you a "tingling" sensation.
