I think our current longest is 6 or 7Km.
Doesn't rain hard on/around the Alaskan mainland though.

Curious
Is 24 GHz subject inversion problems?
How far could a AirFiber 24 go if you don't account for rain fade?

of Florida :)

Let's put this into context... Rain fade varies from place to
place, region to region, you can find specifics about your area
via ITU rain fall charts.
South Florida is listed as Rain Fall 'n' region, part of the worst
group on the charts
24Ghz, is affected by size of the rain drops and how 'hard' it
rains.. (how fast it rains... rain speed ?)
e.g looking at attenuation on 24ghz due to rain, at 2km, it is
0.4db for 1.25mm/hr rain fall, however for the same distance it
jumps to 8db for 25mm/hr rainfall. FYI Rain Zone N can have
rainfall between 5mm/hr to 180mm/hr !)
Airfiber24, will drop link somewhere about -80/-80...
So if you short link has a -40 or -38 signal, then you have 40db
to play with before it drops..
Lots of factors that go into this, and above is a summary listing
of what they are...
This is the reason why, one simply must keep the location in mind,
before comparing someone else's experience...
(unless of-course that someone else is in the same rain fall region).
As we say ... YMMV !

Have AF24 links from .5 to 1 mile and have seen zero rain
fades so far. Set at just under 800Mbps.

I've always wanted to ask this, but if it's across a street
and its high enough, why can you just get a piece of aerial
fiber and a bow and string it?

What is the minimum distance for either one of those?
Have a request for 2 (large) buildings across a street.
