For CB configuration gain is always less than 1.

As in a Common-Base Amplifier input is applied to the emitter terminal and its output is taken from the collector.
Since collector current Ic is always slightly less than the emitter current Ie. The value of current gain (Ai) for this circuit must be less than unity (1).
