You want to stay away from omni directional antennas. Besides the lower 
gain, they dirty up the band real bad. Better to use highly directional for 
point to point and sectorized for cell type distribution. We have rolled 
out several hundred 2.4 customers all over the Sacramento area this way and 
kept the band pretty clean. Our cells range from 1/2 mile to about 3 miles 
in radius. Our directional backbone links go as far as 20 miles, although 
we are experimenting with 5.8 for the backbones now. Our biggest problem is 
those pesky 2.4 wireless home phones. They are nasty.
