All I am saying is when the ends of the antenna are placed near 
the lossy media, losses increase. Because of that, I try to make 
my Inverted V dipoles as flat as I can and I especially try to keep 
the higher current areas as un-bent and high as possible.

I was corrected on this reflector a year or so ago when I failed to 
give importance to the very low ends hurting efficiency from ground 
losses. As I recall, people were discussing the pro's and con's of 
Inverted V vs regular dipoles and the consensus was Inverted V 
dipoles are great way up in the air, but not with the ends down in 
all the clutter and near earth.

I tend to think in terms of high antennas without a sharp apex angle.
