Description <br> The antenna is a wideband helical circularly polarized antenna. Suitable for directional radio signal mission and reception, signal coverage, broadband signal testing and other purposes. <br> 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. <br> <br> Operating frequency: 2.4GHz-5.8GHz <br> Power capacity: 5w <br> Antenna gain: 3.5dBi <br> Radiation direction: antenna plane axial <br> Polarization mode: right circular polarization <br> Antenna impedance: 50 ohms <br> Return loss: Less than 10dB <br> Standing wave ratio: typical value 1.5 <br> Connector type: SMA-K (standard female head, outer screw inner hole) <br> Note: <br> Installation guide not included, we strongly recommend you seek professional installation. <br> Please check as much as possible to make sure the item is what you need. <br> Tips:The product may be updated constantly,Due To Different Batches, The Actual Product May Have Slight Differences Or Color Differences, Which Does Not Affect Use. <br> Colour:As Shown <br> Material:PCB <br> <br> Package Contents: <br> 1 * Lsometric Helical Antenna <br> <br> Only the above package content, other products are not included. <br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
