[CQ-Contest] Twin lead question

[Tony Rogozinski]

I finally found information on the W9INN antennas.  He recommends using Saxton #1562 "Twin Lead" as a feedline
thru a tuner.  I've searched all over the Internet but can't find any info on this wire.  Can anyone tell me what impedance
it would be or know anything about it?  Don't know - maybe I can use open wire line or ladder line?

Please reply direct trogo at telegraphy.com

Thanks
