Jim,
I have copies of a few pages from the Basset Handbook of Rotary Beam Design
for 1939. The Bassett folks had a series of commercial products like a 4
element 20 meter antenna with a rotor for $121. The boom was not round but
looks more like a ladder.
They also had some interesting tower sections that were made of wood. For
$88, you could purchase a 36 foot wood tower that was 3 feet square at the
bottom and 15 inches square at the top. Each tower section was 6 foot in
length.
I'm also interested in other options on the market from this era.
