RE: [WISPA] 900Mhz Grid vs Yagi
Yagi's performance like crap w/ snow and ice on them though -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Marlon K.

RE: [WISPA] 900Mhz Grid vs Yagi
Tom, Check out the newer 15 dbi grid from Pac - it's the same grid as the 2.4 parabolic, but with a 900 mhz horn. It ROCKS in comparison to many other antennas, and I've used 'em all. I'm usin this particular one with Canopy - 12 miles out and -74 through thick trees on the CPE end. 7 jitter!

Hi, I just looked on Pac Wireless' website, as well as Wisp-router and I don't see the 900mhz grid. Do you have a part number or direct link?
