report path Calc result in Number of 9's, it should consider this situation and 
calculate results somewhere in between.

Considering D2 Rain Zone...
Its pretty certain that for 3.5miles, I'd want 3ft dishes.
Its pretty certain that for 2 miles I'd want 2ft dishes.
But for 2.5-3 miles, its uncertain.

NOw I've done the path calcs, and I've has others more experienced than me run 
the path Calcs, for there recommendations. But what I'm looking for is what the 
users in the field found, after running their path Calcs. Did their Link go 
down in the thunderstorm? And was it a little overengineered or little 
underengineered?

  Tom,

  Your rainzone affects potential signal loss during a heavy storm... so it 
takes a bigger dish or more power to compensate for that... just the same as my 
mountaintop towers that get up to 2 feet of ice build-up on them... we have to 
plan for 10db of "extra" signal loss during 3-4 months of the year. 

  I guess I'm not sure why all the questions about multi-path, etc.? I've 
_never_ heard of someone not being able to get an 18ghz link working. It's 
licensed, so there are no noise issues. It's a tight beamwidth, and if 
engineered and installed correctly (not on anything that will move or flex), it 
will work.

  Is there a particular install you are considering?

Multipath would only likely be a concern for tenant building roof mount.

  Hi,

  We currently have five 18ghz links... two have been up for almost 4 years 
with less than 30 minutes downtime total.

  1 - 7 miles, 2ft dishes, 99.% calc'd uptime, so far correct (4 years)
  2 - 19 miles, 4ft dishes, 99.999% calc'd uptime, so far correct (4 years)
  3 - 14 miles, 2.5ft dishes, 99.999% calc'd uptime, so far correct (8 months)
  4 - 15 miles, 2.5ft dishes, 99.999% calc'd uptime, so far correct (8 months)
  5 - 28 miles, 2ft dishes, 99.99% calc'd uptime, so far correct (4 months)

  We have not seen any multi-path issues with any 18ghz links. We are always 
able to get 1-2db better signal than the path calc shows, but it can take a 
little time (the 27 mile link took almost an hour to fully align, compared with 
10-15 minutes for the other links).

  We are in the 12mm/h rain zone.

Very picky.  18Ghz specifically is known for negative effects of reflection, 
that need to be taken into account in isntalltion design.

Any success rates on wall mounting? Are your links path calc'd for 2ft dish

4 - 15 miles, 2.5ft dishes, 99.999% calc'd uptime, so far correct (8
months)
5 - 28 miles, 2ft dishes, 99.99% calc'd uptime, so far correct (4
months)

We have not seen any multi-path issues with any 18ghz links. We are
always able to get 1-2db better signal than the path calc shows, but it
can take a little time (the 27 mile link took almost an hour to fully
align, compared with 10-15 minutes for the other links).

We are in the 12mm/h rain zone.

Very picky.  18Ghz specifically is known for negative effects of reflection, 
that need to be taken into account in isntalltion design.

Any success rates on wall mounting? Are your links path calc'd for 2ft dish 
working with 2 ft, as engineered? Etc.
Are you getting 3- 9s engineering 3- 9's?

This question isn;t about gear, its about 18Ghz.

I wish we could say the same about the Trango.  So far nothing but flaky
behavior and that is with -44 dBm rx signal levels.
But this is a new product to us and there may be something we are not
configuring properly.  Not going to count it out until the factory guys 
have
had a chance to exhaust their remedies.

  The Trango is solid as a rock, also.
Trango is a great product, for a basic config, meaning 1 link, w/ 1
antenna
and radio per side, under 300mbps.
I was nothing but impressed with our units.

Dragonwave currently has the lead from the perspective of supporting all
the
freq ranges in a single paltform, best adaptive modulation routines, and
ability to combine radios on a single antenna to double capacity.  But
there
is a price to that.  If those feature aren't needed?

Cable Free is also a great product, if you are planning on daisy chaining
several links, the flexibilty and cost savings of these units are
fantastic.
Also very impressed with the overall design of their system. (Only
negative
I found was no adaptive modulation)

I have installed over 50 Dragonwave links in the past 24  months.  1
outage the result of equipment failure and I had a replacement in my 
hand
the next day from Canada.

Airpair goes up to 200 Meg. FD. Horizon will do 600 plus. Multiple IDU.
ODU architecture. You could do 200 MB Horizon for your budget.

I have no experience with the trango.

I have used the Trango GigaLink and DragonWave.  DragonWave is rock
solid.
Never a problem.  Have several systems.
We are still trying to get the Trango to play.  Lots of signal but not
running well at all.

  Matt,

I would take a look at the Trango GigaLink 18ghz product. It will do
105Mbps full-duplex (200Mbps total) for your price range and you can do
a software upgrade to 300Mbps full-duplex (600Mbps total) for about
$5,000 extra (at a later date, when you need the speed). It's an 
IDU/ODU
setup and you use LMR-400 between them.

You could lease the 600Mbps version on a 36 month, $1 buyout for less
than you are paying for your fiber. ;)
