Concerning the QST December 5/8th WL Vertical. I had requested from the author more detailed information on the design aspect of the vertical. Henry and the actual designer, Pekka, OH3WAV, have responded with a plethora of design information answering all of my questions and mis-understandingings.
I have compiled all of this information into 5 PDF files of about 5 Mb total. 5 PDF's --The full article, K4ERO Analysis, Chokes for other bands and some advantages, OH3WAV Design Info and OH3WAV Answers to my questions. Some info is probably beyond the current understanding level of a few members just starting out, but it is an excellent teaching moment for them and for other more experienced members. So...if you would like the 5 files please send me a request note DIRECTLY to me. NOT thru the reflector. and I will send them your way. I'd like to hear your comments as you work your way thru the design. Keep us all posted. 73,,,Rick W5RH rickhille...@gmail.com On Thu, Nov 30, 2023 at 3:24 PM Rick Hiller <rickhille...@gmail.com> wrote: > *For those interested in the QST Nov and Dec antenna designs, my note of > Nov 19th requesting insight has been answered by me finding additional > information in the latest QEX for the LPi and the QST Extra Info pages for > the 5/8 wl vertical.
