Using horizontal polarity helps avoid interference from vertical polarity. From what I read/experience a 25db difference. For example, my MT AP is hpol. On a customer site with nice clean LOS was getting -85, weaksauce. I went down, turned it 90 and back up to get -60. Someone built that one without labeling it thinking it wasn't necessary, like I just ask them to do things for no reason. Not that I wouldn't...
