For the sake of multiple conversations at multple sites... [Linked Image] My responce to Don...

Don RG-6's impedance value is based on the center conductor vs the shield and the capacitive effect between the two - if this was on the shield, or likely both, due to skin effect of the current travel you would have something the equivilent of #2 as a path to ground. (Remember the cable was not used as a limited conductor carrying a CATV signal) And the paths to ground could be anywhere... Via the hub to anything (all paths) connected to it, to a phone or DSL modem, computer power supply, through other RG6 connections...

We'll agree to disagree, but I'll maintain that it happened exactly as decribed with the given details.....

I'll add a correction - something equivilent to #4-3...
