I am using a vertical dipole, 10 m above ground for AO 7 mode A and I
have good signals as soon as the bird is 1 degree above horizon. I think
the vertical dipole provides better illumination towards horizon but of
course has a null in the zenith, but that is anyway less interesting for
dx on shortwave and Satellite.
