Wide Band Directional Yagi antenna - Daul Band, 800-2500 MHz, With protective housing shell, has10.5 dB on the 1900 MHz side and 8.0 dB on the 800 MHz side, Has a 45% Beam Point with N-Female Ends and is easy to install."
I think you are being mislead - this is advertised as a yagi and yagi's do not have that kind of
freq range coverage from 800 - 2500 Mhz. If this a dual band yagi for cellular/pcs then it should
be good for the 800 cellular and 1900 pcs bands. The 2400 Mhz spectrum is a bit out of its
intended usage so I doubt that it operates well in that range.
If someone else has one of these please chime in and correct me if I am wrong.
Based on the outline of the radome, I'd say that you're correct. And that being the case, the advertised gain is probably delusionally optimistic. With the crap that Wilson puts out, I'm not surprised in the least bit.
