You're feeding a dummy load - it won't matter.  With RG-8/RG-213
having ~ 1dB/100 ft at 30 MHz, the feedline alone has 500 dB(!)
loss.

Steve,
Change  that to any REASONABLE length, I'll agree, but what happens if
the  length is long enough that R becomes dominant?  I mean, say RG-8,
the reistance of the center conductor is about 1 Ohm/1000 ft.  What if
you had 50K feet of coax? ;)
