The November, 2017 issue of QST has an article titled: "The 75-Meter Dipole Stretcher." As one might guess, it's the author's fix for the age-old problem of attaining reasonably low SWR from a dipole
A correction to my original post: "At 3.6 MHz, the dipole's complex Z is 65.1-j113" should read 65.1-j131. I must have suffered from dyslexia last night. After posting, I ran the same model using RG-
Besides the loss problem you mentioned, a more fundamental problem is that a half wavelength line is only a half wavelength at one frequency, presumably the center of the band. As you tune away from
I never fail to be amazed at the contortions coax obsessed hams put themselves through to cling to that kind of feedline no matter what the circumstances are. Rob K5UJ _______________________________

I feel the same about balanced/ladder line. Wes N7WS Rob K5UJ _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contest
Nothing amazing about balanced line but the people who are inept at how to handle it are amazing. Rob K5UJ _______________________________________________ ____________________________________________
What is amazing is those using webbed "ladder line". I've seen it wrapped around fence posts. It's a good dummy load when old and wet. Transmission line transformers are my friend when needed. Grant

What I like about it is, with a 80m 4-wire cage inverted vee, I don't need to use a tuner. I can QSY with one hand, immediately start operating... and not have to set my beer down. :-D I later remove
Maybe I am 'inept' on how to use ladder line, but I have been using it for 60 years off and on. Problem with my setup using ladder line is noise. Maybe I just don't understand how to use it, but on m
