Consider a 140' dipole fed with ladderline. This antenna is OK on 80 and
above, but very marginal on 160, insofar as loading is concerned.
Now, consider the same length dipole, but with a folded horizontal element
made from 450 ladderline, and 450 ohm ladderline feed. How will this effect
loading down on 160 in relation to the above?
OK, let's go to a 140' folded dipole made with 600 ohm ladderline for the
horizontal element, and fed with 450 ohm ladderline. Will this one load 160
much easier than the simple dipole?
Does going from a simple dipole of a given length to a folded dipole of the
same length give us a better flat bandwidth than the simple dipole has?
