For feeding unmatched antennas like loops

450 ohm twinlead is better than
300 ohm twinlead is better than
coax.

Best of all is open-wire line. I have some home made, comprising 2 
#14 stranded copper wires, held about 2 inches apart by little 
plastic spacers about every 6 inches. It's very low loss .

  The higher the frequency, the higher the power and the greater the 
SWR on the line, the more the benefit. But I think you have to make 
it yourself, I don't know of a commercial supplier .
