I'm not sure what " directivity of the unwanted signals on the coax for the most part are a non issue" means. Antennas have directivity, but signals????
In a well-built system, disconnecting the coax from the matching transformer ought to leave you with no pickup. "well built" means using coax that totally shields the conductor, grounding the shield well, and keeping pickup on the shield from getting to the radio by using "choke baluns". The easiest part to improve may be the coax: Radio Shack sells about the poorest grade of coax made with respect to shield coverage, or used to. I don't see that spec on their web site now.

Craig, I was once told that when you hook up the coax to the receiver and the matching transformer, the directivity of the unwanted signals on the coax for the most part are a non issue. Once you disconnect the coax from the matching transformer or even terminate it, the pick up will be heard. Of course going to double/triple shield or maybe bigger stuff (RG213), hardline may solve the issue too. 73, Patrick Patrick Martin KAVT Reception Manager _______________________________________________ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com _______________________________________________ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
