True statement, but specifically: If the tuner is a high-pass filter, like the common T-network tuner ("ultimate transmatch"), frequencies lower than the resonant frequency of the system (=frequency the tuner & antenna happen to be "tuned to") are attenuated, and higher frequencies (up to a point) are passed with little loss. If the tuner is a low-pass filter, such as the balanced pi-network I use at one of my "studios," frequencies higher than the resonant frequency of the system are attenuated, and lower frequencies (again, up tho a point) work Fine Business Old Man. If the tuner is a band-pass filter - an example would be the link-coupled parallel-tuned LC network popular for tuned feeders - there is attenuation on both sides of the resonant frequency. Brett, by the way, you were strapping into Maine last Sunday morning on 40M - could not fire up to talk to you at the time; I was working on a friend's Ranger with said friend (Steve, KM1V ex-KS1F ex KM1V) in the shack with me. 73, -Larry/NE1S ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list Searchable Archives: http://www.mail-archive.com/amradio@mailman.qth.net/ 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:AMRadio@mailman.qth.net To unsubscribe, send an email to amradio-requ...@mailman.qth.net with the word unsubscribe in the message body.
