Zip cord, at 50 - 72 ohm or so impedance, is a whole lot closer to the center 
fed impedance of a "close to the ground" dipole.
Makes a fair amount of sense, to use it for feedline, clear down to the rig, 
when the rig has a balanced output.. or to the balanced to unbalanced, 1 to 1 
ratio apparatus. And with a stranded, larger than RG-58 or RG-59 coax center, 
it won't have any additional I-R loss than that coax, and our HF freq. And of 
course, making the distinction that we are talking about a single band 
dipole... not a multiband, center fed with what ever the tx is dialed to 
balanced antenna.
