here in Russia, we love cheap cables too, and of cource they are OK in many many cases and serve for years, but I learned hard way and not once that if your need a trouble free life then go proven quality cables and matching connectors
any coax is just a transmition line ... in a receiving systems, transmition lines are allowed to be with some attenuation, but bad connections, RF leakage, watter ingress or a time degradation of a thin copper clad is not allowed YMMV 2012/1/3 Doug Renwick <[email protected]> > Here we go again.
