One reason for the desirability of broad, flat ground conductors at RF, is that the series inductance of such is much less than "round" conductors of any manageable size... While a narrow stricture somewhere in the conductor should be avoided if possible, and it is difficult to avoid entirely, you still gain benefits from the broad conductor contributing less total inductance to the ground system....even if in series with a small run of narrow conductor...

.OK, I've gotten several responses to my station ground question. Nearly all of them have described a ground system with "beefy" (#0 or #2 stranded) wire connecting a bus-bar in the shack to a ground rod (or multiple ground rods connected together), but all of them have described how they connect the rig to the bus-bar using much smaller (like #10) wire. Isn't this a "weakest link problem"? Why do you need "beefy" connections from bus-bar to ground when you use much smaller wire connecting the equipment to the bus-bar?
