Wow ..close... I come up with 132.89 dB FSL and 143.41 dB urban
area FSL ..so I guess if I back out the 2dB loss I am within
1.2dB of the calculations sent to me.
Okay i am close. Cool...I can still add and subtract..yeah me!

I have never had problems using simple free space path loss
for these frequencies.
I doubt there is significant cable or waveguide loss.
Dragonwaves mount to the antenna and the gain of the antenna
is at the interface.
96.6 + 20logD + 20log F Where F & D are GHz and Miles.
96.6 + 10.5 + 25.1 = 132.2 dB

*Subject:* [AFMUG] Smart guys on lost question
Hello Smart Dudes on the list:
Running a 3.348 mile path for 18 Ghz Dragonwave link to
compare what someone else came up with. I am wondering if
they used just unfaded free space loss calculation and coming
up with a figure 10dB better than mine, I am using unfaded
urban area free space loss for mime. I use just free space
loss we are within 3db of each other. I added 1 db of cable
loss since I do not know if waveguide was used or many other
details. I will get all that information on site.
I have always engineered paths on conservative side since the
start.
What are your thoughts Hobson?
Thx
