I am using a twisted  pair, with shield,  that is near  55 ohm impedance for
 my receiving delta loop. The cable is designed for audio,  but looks good 
up
 to 10 MHZ. The KB-5 antenna end transformer has an isolated output. At the
 shack end I wound a transformer with a balanced center tapped winding to an
 unbalanced winding for  my transceiver.  The center tap is for the shield.
 The center tap is floating at the antenna end. It is working well so far. 
See Pennant notes for more
