Paul,
I think you will find that the Coax BalUn cable length is 1/2 wL to get a
180deg phase shift and create the "balanced" feed. When the voltage is "high"
on
terminal 1, it is "LOW" on terminal 2 and visa versa.
The commercial balun should work, but could be inferior to the coax balun for
QRO power.

Now for the matching - the consensus for the T match is something in the 200
ohm range requiring a 4:1 balun which makes sense based on the type of 1/4
wave coax balun shown in the 10 and 15 metre manuals. I assume a
commercial ferrite 4:1 balun could be used in place of the 1/4 wave coaxial
originally specified?
