I own one. It sucks. Of course, mine could be defective, but I doubt
it. The "wrong" biquad works much better. The Airlink Omni worked about
as well as the antenna built in my SMC card.

Which reminds me, I should get around to building the right biquad....

Much depends on what you are trying to accomplish. If all that's needed
is gain, then the Airlink may be a decent and cost-effective solution.
But if part of your problem is interference, then an omni probably won't
help, because it tends to amplify interference along with the desired
signal. By comparison, a directional antenna will tend to reject
interference that's not in line with the desired signal. That's
probably why your biquad, a directional antenna, worked better for you
than the omni. If so, *any* omni would probably be the same.
