Topband: 2 wire beverage - transformers

[N2TK]

I have a few questions about a 2 wire beverage. I am somewhat confused by
the article in ON4UN's book - fig. 7.23A and C and tables 7.9, 7.10 and 7.12

The 2 wire beverage is 10' high with a spacing of 1' vertical with #14 wire
and 580' long.
I gather from the tables this has roughly an impedance of  735 ohms. So, T4,
the center tapped transformer, needs to match 735 ohms to 50 ohms. Is this
correct?

Also, T1 needs to match half that, 360 ohms to 50 ohms. Correct?

The terminating transformer has me confused from table 7.12. I am planning
on using an autotransformer, unless there are reasons why I shouldn't? Is
the transformer matching 735 ohms to 360 ohms?

I plan on using FT114-43 cores.

If someone would be so kind as to tell me how many turns on each
transformer, I would appreciate it. It might help me to not screw this up.

Tnx
Tony
