My house is on a 3.6 450 SM on a reflector. Almost exactly a mile away
to the tower where the standard Cambium OEM 90 degree sector is at 225
feet. I have a large maple tree in the way and skimming another about
150 feet away. I get about -58dBm. When the tree is wet it'll drop to
maybe -67 or so. Compare that with the UBNT 3.65 that I used to be on...
it's night and day. The tree would get wet and I'd be at like -80.
Almost unusable. So I think the dual slant on the 450 helps quite a bit.
Even when the tree wasn't wet and I'd be at like -62 on the UBNT, I
still couldn't get more than 15-16Mbps out of it. I mostly sit at 256QAM
up and down on the 450 and get about 37x11Mbps. 10MHz channel. We have
other sectors in the area so I can't run a 20MHz channel on that sector. :(

Has anyone tried 450 3.65 for near Los situations like this discussion?

Take into account the 24-25dBm Tx power on a 2.4 FSK AP vs 22dBm
on a 2.4 450 AP. And you'll probably get a better pattern on a
sector vs omni. A V-pol omni doesn't typically have a horrible
pattern though. Except for vertical beamwidth. Then you play with
electronic downtilt models, etc. So it's probably moot as far as
Rx power levels go between the two.
We get OK penetration on the 2.4 450 sector we have up. Not so
much the noise at the tower as it is at the SMs. We're going to
get rid of it eventually along with all of the other 2.4 shit.
It's a dead band just like 900 to us now.

Omni to a sector, of course. You're probably getting more than 2
db unless it was a bonkers big omni and super small sector.

I have moved from pmp100 to 450 on 2.4ghz. Didn't do a
cluster though. Went from a 2.4FSK on a 12db Omni to a two
450 sectors from KP 120 beam width (think 14db) . Was able to
hook up every single customer I has on the FSK to the 450 and
some were near-LOS. The 450 in 2.4ghz actually has
impressively decent nLOS. I think its a lot better than the
3.65 for NLOS. ( I have used all the 450 frequency bands
except 900)
If you thinking about going 450 in 2.4 and you already have
FSK up on 2.4 and nothing abmormal with your noise floor then
do it. You'll love it. The 450 is actually better because you
can run 10-mhz channels to get around some of the noise in
2.4 vs the FSK which was stuck at 20mhz

So has anyone moved a PMP100 2.4 cluster too PMP450 2.4
and how did
that go? With PMP100 in 2.4 we do pretty good on near LOS
connections. Only deployed PMP450 in 3.6 and 5ghz so far
though.
