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 info. www.qsl.net/k1fz/pennantnotes.html 73 Bruce-K1FZ ----- Original Message ----- > From: <w7...@juno.com> > To: <topband@contesting.com> > Sent: Monday, August 12, 2013 10:11 AM > Subject: Re: Topband: Zo of an individual CAT5 twisted pair > > > > you fellers dont know what to use CAT5 for, out here in the west we use > it to tie down our pickup loads.............easy to tie, bends well and > is almost indestructible. > > mike w7dra still using an NC183 on topband _________________ Topband Reflector _________________ Topband Reflector
