The KP omni has electronic downtilt. You would probably be better off
ordering a Larsen omni from Last Mile Gear. If it was me, I would just
throw a 450 AP on the KP omni, use up 430 SMs on the longer range
customers that are going to get MIMO-A anyway, keep the FSK up there for
those customers that need it.
If Cambium does actually deliver on the SM-limited 450AP, do sectors
later. Get rid of the FSK. Swap out those 430's that can now get MIMO-B
on the sectors.

Since we have about 25 users total out there, I am going to stick with
the plan of an omni for now. The 5.7 430 is re-purposed from another
site, so free is a good thing.
I have a KPP 13 dbi Omni on the way and will slap that in and see what
I can get. If I can move enough of the higher bandwidth users off of
the FSK AP to balance it all out, it may be a win win situation. The
users that are more than 5 miles out will just have to stay on the FSK
service. Most of our users are withing 3-4 miles anyway.
Thanks for all the good info guys.

He is talking about 430 which may go a bit farther, although
now with MIMO-A mode they are about equal.
Part of the problem is the 450 AP won’t let you set the xmt
power for max allowable EIRP with a low gain antenna.
To maximize distance, I might use 450 instead of 430, and a 10
MHz channel in 5.7. 450 starts out with 6 to 8 times the
capacity of FSK, so even cutting the channel width in half,
you still have a 3 to 4 times capacity increase, and you gain
3 dB of system margin which should get you out to 5 miles
instead of 3-4 like Sean says. You could even go to a 5 MHz
channel.
If you find the omni isn’t giving you enough capacity, maybe
you have a cluster of high bandwidth users in one direction
and you add 1 sector. Eventually if you get enough subs, you
can fully sectorize.
There was a rumor from AF about a Lite (10 SM) AP from
Cambium, upgradable with a license key. If true, this would
make sectors an easier decision. Although you still have to
buy antennas for them.

you will only get about 3 maybe 4 miles out of a 450 with an omni

I know I know, don't use it. But in this case, I have to.
Plus, we only have 25 Customers at this site on a FSK 5.2
AP. And I am looking for the same coverage area (roughly 8
mile radius).
The FSK does surprising well on a 9 dbi L-Com antenna at 8
miles.Inline image 1
1st column is uptime. I rebooted the AP yesterday.
Yesterday I installed the AP with a UBNT 10 dbi OMNI and
the Range sucked. -82 at 3.1 miles. It's what I had on hand.
I am looking for twice the distance at -79 or better. This
is a SUPER Rural area with no noise.
thanks
