ATU are very low impedances.

If you think about your own requirements, and finding a solution that
fits, you will do better than Googling up HamUniverse articles and the
like.

When I calculate the feedline length am I correct in assuming that I
need to take in to account the velocity factor of the 460 ohm ladder
line?
