So, I would have balanced open-wire feedline from the dipole to

See my article entitled "Is a 4:1 balun a good choice for use with an ATU
on HF?" at http://vk1od.net/blog/?p=987 .

It is difficult to answer the question about the LDF without knowing the
impedances involved. I used TLLC ( http://www.vk1od.net/calc/tl/tllc.php )
to work the examples I gave, you could do the same if you know the
feedpoint impedance etc.

If you want to solve the cases for an arbitrary two wire line, try
