The gain and pattern will be very close to that of a dipole at a height

What's a point incident antenna?


Hi Roy, I consider it the radiation point of a "0" length element
which radiates in spherical direction.


Careful there. A "zero length" (or infinitesimal) dipole (aka a
Hertzian dipole) does not have an isotropic (spherical) pattern. It has
1.64dBi directivity, as I recall.
