"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 groundplane would seriously outperform the I-MAX 2000 or any other 1/2 or 5/8th wl antenna that does not have a large groundplane.

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."

im no imax or 99 fanboy , but there are tons of folks that use them and have compared them to maco and other 5/8 antennas with 1/4 wl ground elements and the imax excelled both locally and skip wise for them . and theres others that had the exact opposite results with the imax loosing .

seems to be a contradiction between w8ji's post and the real word results of a lot a folks . or im misunderstanding something .
