Atop Technologies' provides a variety of single and dual band 2.4 GHz omnidirectional antennas for any application. These antennas come with cable type and length (150 cm, 180 cm, and 200 cm) options as well as various connectors such as RP-SMA(M), RP-SMA(F), and N-type(F). These antennas have typical gains from 3 dBi up to 9 dBi, depending on model, with max power handling of 15 W for ANT-WS-A-NF-09 and ANT-WS-A-NF-09-150. All antennas have 50 Ohms of impedance. The ANT-WD-A-RF-0305 comes with a RP-SMA (female) connector and is 160 mm tall. The ANT-WS-AB-RM-05-180 and ANT-WS-AB-05-200 both come with RP-SMA (male) connector with cable lengths of 180 cm and 200 cm long. The ANT-WS-A-DF-09 and ANT-WS-A-DF-09-150 have N-type (female) connectors with the ANT-WS-A-DF-09-150 having a 150 cm long cable. The ANT-WS and ANT-WD antennas are great choices for 2.4 GHz / IEEE 802.11 radios.
