Antenna modeling tools aren't intended to model propagation effects. But
the stronger the signal radiated in the right direction, the stronger
the received signal will be. And the strength of the radiated signal in
each direction is what the antenna modeling program shows.

As for the "effect of capture area", the "capture area" of an antenna is
just another way of stating the gain. This information is what you get
from an antenna modeling program.

More like model has a problem capturing or reflecting reality.
Modeling will calculate the pattern etc., but will not properly reflect the
interaction of the antenna design with propagation medium and
terrain/surroundings, like showing effect of capture area.

Rhombics perform better than what simulations and modeling show.

I can vouch for that. .............
Problem with the model??
