Think how much better it would be with a decent Vertical dipole;-)..

Who knows why they use these halos?,

1. Halos are compact and very easy to mount on (around) a vertical mast.
They don't clutter up the space required for other aerials too much.

2. Halos have a well-defined, pretty well omnidirectional gain of around
minus 3dBd. The fact that that there a minus sign there doesn't
necessarily indicate that it doesn't perform adequately.
