I want to make sure everyone has the correct information on this topic. 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).

Coaxes and attenuators only. I've used antennas and bare SMs 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.
