Yes, but I bet your model did not (properly) include the _feedline_.
Unless this feedline is _seriously_ loaded with common-mode chokes,
it carries substantial common-mode current, which not only radiates,
it also feeds RF current to the AC power wiring of your house. The
result is not only undesired radiation, but also dissipation and a
high received noise level.
