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.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-5.8GHzPower capacity: 5wAntenna gain: 3.5dBiRadiation direction: antenna plane axialPolarization mode: right circular polarizationAntenna impedance: 50 ohmsReturn loss: Less than 10dBStanding wave ratio: typical value 1.5Connector type: SMA-K (standard female head, 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.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.Colour:As ShownMaterial:PCBPackage Contents:1 * Lsometric Helical AntennaOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
