So, how do I achieve that ideal "single point ground" in a situation
like this?

As I understand it, a "single point ground" means that everything is tied
to the same ground system however big or small that is. What you don't
want is the shack tied to a ground and the tower to its own ground with
the cabling tying the two together. The result will be unequal potential
at the tower and in the shack. A "single point ground" reference means
that the potential everywhere will be the same, rising and falling
together in the event of a strike.

I have seen it recommended to make that 50' run of #2 stranded copper and
place a ground rod approximately every eight feet along the run (no
closer than eight feet). You will have a much improved lightning ground
*and* a "single point ground". Beating a bunch of ground rods in the
ground is of little value unless they are at least eight feet apart.

Poke around Polyphaser's Web site for more detail information.
