Query: Not much better than a stock antenna

I have this antenna on a Dlink access point, and the benefit is only about 2-3 points improvement on the signal strength meter (that goes from 0-100%) compared to the stock antenna. This is such a minor improvement that I had to make very careful measurements just to convince myself that it was helping at all, since moving the AP a couple inches or tipping it a few degrees can make a 10 pt difference. The AP had a signal strength of 20% (receiving from a distant wireless G router) at its best position with the stock antenna, and this antenna got it up to 22 or 23. When I connected the antenna with the included cable (instead of directly to the AP) the cable loss was such that I couldn't even get a 20 anymore. With an advertized improvement of several dbi better than a stock antenna, I expected that 20% to become a 40 or so, but no.
