And that's exactly it... for low takeoff angles, a horizontally 
polarized antenna is almost always better than a vertical of the same 
physical size at the same height above ground.

WHen it comes to low bands, where building a full size antenna is 
difficult, then other factors come into play. It's esier to build a 1/4 
wave vertical for 80m than a 1/2 wave rotatable dipole (or pair of 
switched dipoles).. and it's hard to get that dipole up in the air.
