Hi Walt,

Yep, you've got Chipman nailed down! His tome is one of my bibles. The
others
are Kraus' Antennas, and Ed Laport's Radio Antenna Engineering.

I have Kraus' book (the last edition printed! -- now that Dr. Kraus has died,
it'll be interesting to see if Ronald Marhefka releases another edition of
it?) and Laport's book from
http://snulbug.mtview.ca.us/books/Ra...naEngineering/. Is that the same
scan you have?

I tried to build a 2.4GHz helical antenna based on the information in Kraus'
book some 3 or so years ago now, but unfortunately it didn't work. Having
access to a network analyzer these days would probably improve my odds...!

Thanks,
--Joel
