I just want to make sure that I understand clearly what that video is stipulating ....
and Josh, yes there is family of sector antennas (a bit funky looking) which have these specs.. + a few other very interesting design features. I have been looking for more technical info explanation as to why they are supposed to be 'awesome'... This video provides an independent, solid non biased tech opinion as to why. Just looking for confirmation of my understanding..
