Hi Frank, KB1QZH
The best starting point is the original article of the inventor of QHA i.e
Walter Maxell, W2DU
In a separate email I have attached the above fundamental article.

I have a question along the same line. Is the QHA in the ARRL
Satellite Handbook \ Antenna handbook, a good starting place?
Thanks,

This is a reminder that the AMSAT Symposium is quickly approaching.
It takes place next weekend (9-11 OCT) at the BWI Sheraton and you're
invited!
This Symposium marks the 40th Anniversary of AMSAT and we'll be
celebrating this significant milestone along with looking forward to
the next 40 years. AMSAT members who are registered for the Symposium
are invited to a 'birthday party' for AMSAT Friday evening (including
a birthday cake). In addition, Symposium attendees will also receive
a 40th Anniversary History of AMSAT written/edited by Bill Tynan, W3XO
in their registration packets. Many of us don't know the 'story of
AMSAT', and thanks to the work of Bill Tynan, Dick Daniels, Keith
Baker and others, we've focused this year on telling AMSAT's story
through their articles in the AMSAT Journal. Bill's new book provides
significantly more detail as well as brings the reader right up to the
current year. It makes for fun reading and gives recognition to the
significant achievements over the past 40 years!
This year's "AMSAT Proceedings" has a wide assortment of papers and
this year's presentations will be both interesting and informative.
Dan Schultz, N8FGV is finalizing the "Proceedings" as this is written
and attendees will be in position to hear the presentations, discuss
the papers with the authors, and gain some insight into the future
direction of AMSAT's satellite program.
The Saturday evening Banquet will feature Martin Collins, a curator at
the Smithsonian Air & Space Museum. The title of his talk is "Making
the Space Age: The First Fifty Years".
A reminder that that the AMSAT BOD meeting takes place Thursday, 8 OCT
and Friday morning, 9 OCT. This is an open meeting, though the BOD
does go into closed session briefly on Friday morning. In addition
the AMSAT Annual Meeting takes place Saturday afternoon 1530-1700
EDT. We expect to have the Annual Meeting 'online' via Echolink. I
anticipate that both the Symposium and the Annual Meeting will be an
opportunity to highlight some of the significant accomplishments that
have taken place over the last 12 months plus give some perspective on
the future direction of AMSAT.
Please consider joining us to celebrate a significant milestone for
AMSAT and build the foundation for the next 40 years! You may
register online at the AMSAT Store:

It's great to see the diagrams of ARISSAT-1 up on the web site:
congratulations to KF4KSS and everyone who contributed. Can anyone
describe the nature of the experiment from Kursk University that is
going to be included in the satellite?
