Antenna gain comes from squeezing the same energy into a smaller space.  So if you connect two 30 degree horns with a phasing harness, then you now have something smaller than 30 degrees.  Same effect as a bigger antenna.  I don't know how you predict what the new pattern looks like, but I'm betting if you stack vertically you're narrowing the elevation beamwidth.

The only phasing harness I've seen in real life was four VHF yagis. To gain 3db on a yagi you'd make it about twice as long, so it must have been more mechanically feasible to set up 4 yagis in a square than to make the equivalent jumbo size yagi.

I was under the impression that by phasing 2 antennas you achieved 3db more gain (tx and rx)

Double the gain or double the power with the 3 dB? Increasing the gain is going to narrow your beam no matter how you slice it.

Thank You,

Gino, what are you trying to accomplish and what AP are you using to do that with?

Easy for you who can fabricate anything on a whim! :-)

Easier to just continue with the cone making it longer.

    Whats the distance for 5ghz? Wondering if I can bond 2 RF Element
