(score: 1): Author: David Cole <dave@nk7z.net>; Date: Fri, 20 Jun 2014 04:53:57 -0700; Hello all, I have a friend who added two of the Fair-rite 31 mix Ferrite's to a cable running between his rig, and his tuner, one on each end of the cable. His antenna is a OCF Dipole roof mounted. O; /archives//html/RFI/2014-06/msg00117.html (7,242 bytes)

(score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Fri, 20 Jun 2014 09:18:42 -0700; First, because it's off-center fed, it's wildly unbalanced, so there's a lot of common mode current on the feedline, which makes it part of the antenna. The path for that current is through the tuner; /archives//html/RFI/2014-06/msg00120.html (7,559 bytes)
