Well Rick I started out with the antenna in the NOVEMBER QST page 35. I had to delete the 98” wire to make it run. With that wire it did run but with very poor VSWR. I added that wire back in 12” segments and somewhere between 2 and 36” it chokes after a short run speaking of a negative calculated power ( Flux capacitor failure?). At one point I did get VSWR dips at each of the ham bands but 8:1 at best and only 100 kHz wide. I am sure the antenna is good but I am missing something or something didn’t make it to print.
As for the December antenna I am not good enough with Eznec to use the coax connections. I would love to see your file and how you built your file. On October 31 you spoke of Auto EZ. I sounds like a very useful tool to handle the multiple runs it takes to bring an antenna on to frequency and optimize desired results. While I know Excel well enough to make a spread sheet I don’t understand the syntax that is spoken of. I need some help. I love the program and antenna modeling and know I have much more to learn.

Most are straight forward and have a reasonable explanation of how the antenna works. The Dec 2023 QST has the "OH3JF 5/8 WL Vertical Dipole". He tells you what to do to build it (sort of) but doesn't tell you what makes it all work. I have looked at it every which way to no avail. The numbers just don't match to a 5/8 wl antenna and I do not understand the reason, values and positions for the capacitor stub and the "matching stub". Best guess he is shortening a longer antenna to 5/8th wl ...no....forget I said that....I just don't know. I look at the added info he references and that gave no clue either. I'll keep digging. (Unfortunately, as a non--native English speaker his grammar is not so hot) Anybody out there have a different take on this antenna's design and theory? I sure would appreciate being set straight. Thanks and 73...Rick W5RH
