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.
