So I have used many different types of antennas so far, roos, grids, omni's, yagi's, sectors, etc.
I bought an 18dbi yagi antenna (antennex I think) and it actually wasn't any longer than the pacwireless 13dbi. the biggest difference was the size of the prongs on it. much thicker aluminum. I've also noticed that the mt panels are thicker than the roos I use, same surface area though, and their gain is higher as well.
So I know that physical size of antenna increases gain, how about composition?
I also have a 13dbi vpol 900mhz 130deg sector which is massive and very heavy compared to the 12dbi hpol 120 deg sector I got from superpass... maybe they're stretching the 12dbi rating on the superpass antenna?
