I have a book "Yagi-Uda Antenna" by Uda. The forward was written by
Hidetsugu Yagi. Here is a quote from the forward by Yagi.
"The so-called Yagi-Uda antenna, consisting of wave-reflectors and
wave-directors, was first presented in a publication by one of the
co-authors of this text (Uda) and the writer during the year 1926" Amazing.

Interesting.. What was the design of the 4 element antenna? I don't
know that Yagi-Uda design was known by then, certainly not widely.
That was a pretty pricey antenna.. $121 in 1939 is $1771 in 2006 if
you use the CPI
