For 40 meters and upwards, you can easily model balanced feeders as 2
parallel wires. (e.q. see tltest.nec as example in the 4nec2 package). If
you are not interested in additional losses of pattern influence resulting
from the feedline, but just in input impedance you can use the TL card
without problems.
