Yes. Because antenna connected via technologies MIMO. I think to change one will not make sense.

I think yes. But on the forum lan23 you've posted calculations dual band antenna, Harchenko with increased 10-18, Dbi. I think it more interesting.

This is something about what I said. I think it better. If wrong, it is correct me. You have left the drawing from her? Immediately asking for this antenna have to do such a reflector in the form of a cup or you can make two antenna for MIMO and placed them in a rectangular box?

I think it should look like this, but it need to make a 250 Ohm adaptation...

Afraid to sound rude, but I think complex in the manufacture of the antenna. Can be will be easier to do patch antenna with increased 15 dbi? If You will not difficult.
