Slide didn't come though. Picture the new ePMP 2000 sector antenna with
a 450i AP turned backwards and mounted directly on the back of the
sector. It's hawt. I want 3GHz too, Matt!

Darin - It was true that when it was first launched, and we had the 90
degree Mars sector antenna, the front-to-back of that antenna was not
good enough to do frequency re-use.
However, the current shipping integrated Access Points (part numbers
ending in “B”, e.g. C050045A006B) have a Cambium Networks-designed
antenna attached (more like a standard tall and narrow sector, rather
than a 14” square flat panel). This antenna was built with frequency
re-use in mind, and is optimized for use with the 450i platform. It
is a true 90 degree sector, and eliminates the need for jumper cables
as George mentions.
I have attached a slide highlighting this (if it comes through).

Be careful with the integrated 450i though as the FTB isn't good
enough for gps sync according to cambium.

Accuracy. Known-good connectorized SMs to verify multiple APs in 3 and

pointed up at the ceiling and it's just not reliable. We ended up
redeploying an old AP that apparently has bad Tx on one polarity.
Really
trying to cut down on the BS and multiple tower climbs. Also getting
really sick of weather-seals leaking for no apparent reason. Which is
another reason I'm not so mad about the 450AP going away. We'll
probably
just start using that fancy new 450i integrated 90 over time. No
coaxes
to worry about with that.
