Of course I feed the 50 ohm coax to the link. The center to one side of the link and the shield (ground) to the other. What effect does the "link position" have on a tuner? I suspect the link position (mine is rotatable) would affect the matching impedance to the coax? 73 Brian / wa5am ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
