Sure.
Why not just use an omni and an amp? 500mw amp and 8dB omni is 35dB.

The Hypergain antennas on the site range from 180* 15dBi sector with 10* vertical beamwidth to 90* and 120* 20dBi with 6.5* vertical beamwidth. Seems as though that would take some mighty careful aiming. Would it work to put one of these high gain sectors aimed at just under the horizon for long shots and then have a lower gain aimed in the same direction but more downtilt for closer customers? Different channels, of course.

I thought that the maxrad adjustable sector might be the hot ticket for
you.
You can get 90* sectors with pretty high gain.17dB or so. For a short
coax
run I count connectors etc. as 0dB. If 2dB makes a difference on your system, your in trouble anyway.
Make sure not to get too high of a gain. You don't want to end up with
a 2*
vertical pattern!

Thanks for the feedback Nish. I really didn't make it clear in my
original
post but I need to build an AP that covers at least 90 degrees and as
much
as 180 degrees. This implies that I need a sector antenna of some sort instead of a directional parabolic.

Why not consider 19 or 24db parabolic? They are certified. You can turn down the output power a little bit with Dial-aPower. <http://www.smartbridges.com/new/products/antenna.php>

I'd like to be able to deploy a maximum legal power point to
multi-point
AP using APPO. I believe the FCC will allow 36db ERP in this configuration. The APPO generates 17.5 db at the antenna connection.
The
maximum approved sector antenna is 16.5 db from PacWireless. This
gives
us 34 db but we need to subtract perhaps 2 db for connectors, coax and
the
like giving us 32 db.
It looks like we could use a 20 db antenna to really make an APPO sing. Are there other antenna's that are not on the 'certified' list that we could legally use? Does anyone have suggestions for specific antennas?
Thanks, Greg
