"Most of the radiation is up in the sky at a high angle. The angle is so high, it is even useless for skywave.

This is a NEGATIVE gain antenna at low angles. A 1/4wl ground plane would seriously outperform the I-MAX 2000 or any other 1/2 or 5/8th wl antenna that does not have a large ground plane.

This pattern is over real earth, where a conventional dipole has about 8 to 8.5 dBi gain. This antenna about -2 dBd gain maximum. It has negative gain over a dipole. The gain over a dipole at most useful angles for DX is about -10 dB....significant negative gain."

I'll give you this. Any of these antennas (A99, Solorcon,Imax) are better than no antenna but nearly any antenna is better .
