Choosing this model
GL450UIA selection guide
GL450UIA does not offer a listed RF advantage over GL450UI or GL450UIB: all three share the same electrical figures. Its distinguishing differences are its longer body and greater weight, so check physical fit before selecting it.
GL450UIB is shorter and lighter and, like GL450UIA, lists SMA male or a customized connector. If a standard SMA-male connection is sufficient and minimum listed length is the priority, compare GL450UI as well.
