Niels Bohr said it well:

"The opposite of a correct statement is indeed an incorrect 
statement.

But the opposite of a profound TRUTH may well be ANOTHER 
profound
truth..."

If you wad each full-length wire up into a ball and mount 
the feed point 5
feet from the ground, no amount of fancy feedline 
transformation will make
the antenna EFFECTIVE for DX or even serious real-world NVIS.

Conversely, if you have a really nice half-wave dipole at 70 
feet with little
or no impedance matching, it's down to random chance that 
the feedline
length is JUST RIGHT to make it play as well as it would 
WITH competent
matching like you get with a well-thought-out current balun 
and/or a tuner.
If you mount the antenna end-on to the desired direction, 
you might also get
disappointing results, unless it's a SLOPER... but which way 
is it sloped, and
which way did you want the RF to go?

Most arguments result from an unwillingness to accept the 
validity of the
other person's input. Too often folks are hung up on "being 
right" and
therefore, the other person is "wrong." Constructive 
arguments are the
ones that seek new knowledge and are centered on LEARNING rather
than criticism or invalidation.

I say the thing to do is experiment with some real antennas, 
and see what
you get. The laws of physics will reveal the TRUTH(S).
