Hi Don,

That's a common perception, but it isn't totally true. There isn't 
significantly more tilt to the horizontal component in an Inverted 
Vee dipole than in a conventional dipole at the same effective height 
broadside to the antenna.

The main change offered by an Inverted Vee dipole is a slight 
increase in signal level off the ends, and a slight lowering of the 
effective height of the antenna. Broadside to the antenna it is all 
horizontal polarization, just like a regular dipole.

Even perfectly horizontal dipoles have a tilt to polarization as we 
move away from broadside. Directly off the ends, all radiation is 
vertically polarized but it is well attenuated.
