How are y'all running "G" in so many places? I would love to implement G, but I have so many towers sectored out and then we have so many clients running wireless routers close to the CPE that I feel like there would be trouble in Paradise here!!
Are any of you running G on anything but an Omni antenna? (Multiple antennas on one tower?)

A bad G link will still give as good as a GOOD B link. G will give 5 mbps even when it is close to not connecting and B requires superb signals to get 5 mbps.
