These are quite irrelevant questions, unless you specify the height of
the antenna (in wavelengths) and the characteristics of the ground
(mainly conductivity) at the frequency of interest.

For instance a horizontal dipole more than 10 wavelengths above ground
would have quite omnidirectional pattern in the vertical pattern, but
nulls in the direction of the elements. Of course, this can be a bit
hard to implement on 135 kHz, but not a real problem on 1,3 GHz :-)
