Frequency range is 2.4 GHz - 2.5 GHz. Bandwidth is (2:1) = 135 MHz / (1.5:1) = 75 MHz. VSWR at center frequency is <1.1:1 typical. Impedance at center frequency is 50 Ohms typical. Gain is 5 dBi/2.7 dBd typical. Length of the antenna is 7.3inches typical (straight) / 6.25inches typical (at 90 degrees).
