The antenna is a wideband helical circularly polarized antenna. Suitable for directional radio signal transmission and reception, signal coverage, broadband signal testing and other purposes. The antenna working frequency covers common frequencies such as UWB positioning module and Wifi. Its circular polarization characteristics can reduce the effects of multipath effects. Operating frequency: 2.4GHz-5.8GHz Power capacity: 5w Antenna gain: 3.5dBi Radiation direction: antenna plane axial Polarization mode: right circular polarization Antenna impedance: 50 ohms Return loss: Less than 10dB Standing wave ratio: typical value 1.5 Connector type: SMA-K (standard female , outer screw inner hole) Note: Installation guide not included, we strongly recommend you professional installation. Please check as much as possible to make sure the item is what you need.
