An 8' dish is way over 500 pounds. Do you have any idea how expensive
it is to put an 8' dish on a tower??? And have you calculated if the
tower can even take the new wind loading of an 8' dish at EIA/TIA 222G
calculations for its exposure category?
Weight aside the wind loading of an 8' dish is considerable.
If you do end up hanging the thing from a man lift I want photos,
because there are a few OSHA inspectors I would like to give
nightmares to.

Yeah, but what if it doesn't work with the 8' dish? once you
have some kind of a link in place, it's pretty easy to get a
good idea of what's going to happen when you get bigger dishes
on there.

Putting up an 8' dish without having any idea what it's
going to do seems kind of risky - I'd assume that's not
going to be cheap to put that up. I would want to put up
some kind of a test link before I went there, even if it
was just a pair of PowerBeams.

Cambium LinkPlanner would help you get a good guess of
your outcome, use the PTP 25600 Radio as a AF2 replacement
in your calcs, add the foliage and voila!

Not in this case. If they won’t let me put a 1 or 2’ dish
on the tower they run to get extra bandwidth to the school
(7 T1’s for 300 kids) or the medical clinic (2 T-1’s), I’m
thinking they aren’t going to let me cut down or trim a
mile of trees.
Everytime I proposed something I was answered with “we
have a plan, just be patient”. Not really my strong suit.
This plan involves towers but nobody knows who gets
awarded or when. So, 2.4GHz through a mile of trees,
here I come.
I thought of the 2’ dish and see what happens but I don’t
want to have to pay tower climbers so do this twice. I’m
going to do the 8’ dish on the tower and 2’ dish on the
roof. Once I see those numbers, I can make adjustments on
the roof. Biggest issue is AF2 through trees. I’m
thinking that I’m bringing up a pair of ePMP 2.4GHz radios
also to compare. I’m also considering putting up a
Cambium 450i 900MHz as backup with a Yagi.

Actually, you would be surprised. I have asked them to
remove trees in a microwave path before and they had no
problem doing it.

Have you considered the rigging/hoisting and mounting
costs of 8' dishes, vs chainsaw or doing something more
creative in dish location with 2.5'/3' size dishes to get
real LOS?

Gain is never an exact number as it always varies over the
covered frequency range and polarization, but from what I
understand Ubiquiti overstates their gain by 2-3 db over
the 'industry standard' measurements. Similar to how they
say the AF24 can go up to 10miles, which is effectively
bs, the max 99.99% availability reliable range is 3-4
miles almost anywhere on earth that a substantial number
of those radios coild be installed.

there is another fundamental difference, but the L-Com
900mm dish is only rated at 25 dBi.
I have not used it, but I've been happy with their 400mm unit.

gathering unwanted 2.4 noise from the sides...
