Sean,
Would you post scans of those 4 pages in the Files section in a "Yagi-Uda" directory?
There's a FORTRAN code by Morris. I'm still looking for his dissertation.

I'm going to see what I can get. It's currently not scanned, but DTIC and the other DoD archivists have been very helpful in the past. I'd love to see a coordinated effort to make stuff like EM-3333, the multiband dipole research done around 1970 into an organized archive and readily available. The ARRL Antenna Handbook discussion is quite lame in comparison.
My entire day has been spent doing battle with a failing HP Z400 running Solaris 10 u8 which has been in near 24x7 service for 10 years. :-(
I've been thinking about the conductors on elastic threads experiment. I need to make a couple of baluns so I can place a pair of dipoles at asymmetric distances from the ends and feed a step from an SD-24 into 1 dipole and monitor the other dipole with the 2nd channel.
In the 1920's numerical methods were simply not possible, so how did they develop the concept?
Have Fun!

Indeed, and I think I have most of them in my library.
Today, I had the foresight to grab both volumes of "Antenna Theory" from my office at work. Parasitic arrays are discussed in Volume 1, pp 402-406. Reference is made to a paper called "The Long Yagi-Uda Array" by R.J. Mailloux appearing in the IEEE Transactions on Antenna Propagation, Vol AP-14, pp 128-137, 1966 as well as "Optimization of the Yagi Array" by I.L. Morris, his doctoral dissertation from Harvard, 1965.

Collin was a somewhat prolific writer of text books about EM fields, propagation and antennas. I think he was the author or co-author of six or seven different books.
