[TowerTalk] Why horizontally polarized antennas?

[David Gilbert]

That's one good reason for it.  Another is that in the case of only one 
yagi, mounting it vertically puts all the elements in line with the 
tower/mast, potentially causing unwanted electrical interactions.

Another is that vertical elements (long at HF frequencies) would tend to 
interfere mechanically, assuming you wanted to rotate the antenna, with 
guy wires or any wire antennas (80m dipole, etc) hung from the top of 
the tower unless you used a really long mast.

Another is that horizontally configured yagis for other bands (or phased 
for the same band) can easily be stacked one above the other on the same 
mast.  Imagine mounting three vertically configured monoband yagis one 
above the other.
