Their claims and their diagrammed configuration don't really fit together for me - I'm
not sure how they are acheiving the "phased array" effect, and the gain is very low
for such an antenna (or even for a "steered array" system.) I may be mistaken, but it
resembles an AP being switched between a series of 90-degree "etched bow-tie"
radiators, depending on where it perceives the signal source/destination to be ("cube"
and "tower" designs on their web pages.) The problem with that observation is that
their info suggests a lot tighter beam-width.
Are they claiming to be effective competitors for Vivato?

I'm still trying to determine what provides the co-phasing.
At first blush, it looks like a switched antenna system to me. Also,
the gain ("10dBi over an omni with the same pattern"?) is fairly low.
