[Elecraft] KX1 - We need to develop the ideal antenna

[Dale Putnam]

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.
