Don't do it for that purpose unless you are putting all of this at the top of a 1000' tower on top of a 1000' cliff overlooking the area you want to serve. You'll be wasting available channels. Get a good sector antenna with a reasonable ( >10 degrees ) vertical beamwidth. Unless of course you are planning on having 500+ customers aiming at this one location. Then I could see the advantage of distributing them across several radios. One good antenna/radio setup will serve a very large area as close in and as far out as 2.4GHz is capable of traveling. You'll have so much overlap it's not even funny.
We're using a Maxrad 90 degree sector antenna that has a 14 degree vertical beam. By tilting the antenna down about 7 degrees we have the top of the signal pointing directly at the horizon. That gives us coverage from that point 14 degrees downward. It doesn't sound like much, but we are able to pick up customers as close in as 2 blocks from the tower, and as far away as 12 miles from this one antenna. Put one antenna up and test it. If it does what you want then it was worth the effort.

Using 3 120* created a lot more overlap than you think and can cause strange thinkg to happen to your signal pattern. I believe that Scott recommends 3 90* sectors for 360* coverage, but you would have to ask Scott to be sure. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dan Petermann Sent: Thursday, July 17, 2003 9:34 AM To: [EMAIL PROTECTED] Subject: RE: [smartBridges] AirPointPRO TOTAL That is what I thought. I've been looking at setting up 120 degree sectors. I like the high gain but the vertical beam width is just too narrow. 6.5 degrees! Or is it 13? (+/- 6.5) I'm looking at getting the Maxrad MS024014PTNF (sectorized omni). Has anyone used these? Any horror stories to be aware of? This will be my first sectorized site so I'm hoping for great things. Dan Petermann Wyoming.com At 09:05 AM 7/17/2003 -0400, you wrote: >With that small of a VBW ?
