Thanks for some excellent ideas guys.

I will make sure to check the transmission retry count today as David Young
suggested.

As Chris Beaumont had suggested we had considered trying to get rid of the
(2) 20ft. coax runs.  One method was to move the WAP11's into a sealed
enclosure and then use D-Link DWL-P100's(good cheap PoE units) to power it.
The other option was to use the other bridge units I mentioned in the
original article.  They were designed for outdoor use so would require
minimal shielding.  According to calculators I ran though, just eliminating
the cables wouldn't gain me that much signal.

Charles Chia Seng Wu suggested Karlnet or Star-OS, and we looked into
Karlnet in the beginning and found it cost prohibitive.  We are a very small
school district and the budget was tight.  The project was just to get some
better internet speed to a school in a small town where the option is either
dial-up or T1, and the T1 costs $2,300/month.

Jason Straight commented on height, so I will clarify that.  On one end the
WAP sits in attic area of a home sized building, and the cable runs up a
mast right next to the building.  Overall height on that end is 35 foot.  On
the other end the WAP sits in the attic area of a 24 foot building and then
the cable runs through the roof and up a tripod that is mounted at the peak
of the building.  Overall height on this end is 40 foot.  At the beginning
of the project we had a local GIS person gather some topographical maps and
we discerned that there is a small "valley" between the sites(luckily) and
that there is a steady 80 foot drop from site 1 to site 2.  We came up with
about the same Fresnel of 43ish feet, but according to our numbers the only
problem is at site one where we only have 35 foot.

Again, thank you for the excellent suggestions.
