A wire is a wire is a wire. Unless it's a transmission line when it's just a transmission line.
I suggest some exploration of the ham radio world. Try the forums. With the frequencies and powers involved, you may expect that these folks are "into cables" too. Like having some boutique brands of coax, connectors etc. that promise to let them reach Antarctica with only 1 Watt - by "easing the flow of electrons to the antenna through nano-molecular alignment of cable crystalline network", "reducing noise by tuning thermal noise out of band" or some other BS.
Well they're not. While they do discuss stuff like electrical/mechanical parameters, weather resistance and such, they're *not* into magic cables. For them a 50Ohms cable is a 50Ohms cable of specified diameter, loss and maximum power.
Wonder why? Maybe just because them ham radio guys also tend to have measuring instruments in their shacks and don't need to do it "by the ear".
Or maybe we should try to educate them, eh?
