    What’s the difference of combining bypass and WBC for ultrasite?Can a 2/2/2 site without WBC and uses bypass combining only? To do extension such as 2/2/2 to 3/2/2,3/3/2,etc, what’s more must be needed except the TRX?BB2 and M6?Is that right?Thank u!


    When you use WBC, you lost 3db.


    site with 2 antenna=> bypass (222 max) if you want a 3nd, you must use WBC.

    on antenna 1 => tx1 rx1 div2
    on antenna 2 => tx2 rx2 div1

    site with 2 antenna => WBC (444 max)

    on antenna 1 => tx1, tx2, rx1, rx2, div3, div4
    on antenna 2 => tx3, tx4, rx3, rx4, div1, div2
