Ultra-wideband helical antenna, left/right-handed and SMA connectors are all available, shipped by default, the connector is an SMA female external thread inner hole. Ultra-wideband 510MHz--10GHz helical antenna This antenna is an ultra-wideband equiangular helix, divided into left-hand circular polarization and right-hand circular polarization antennas. It can be used for direction finding, spectrum analysis, signal analysis, navigation positioning, broadband measurement, direction finding, etc., providing 3-6dBi circular polarization directional gain in the frequency band of 900MHz-10GHz. Low standing wave, high gain, and significant performance. Typical operating frequencies are: 915MHz, 1090MHzADS-B, 1268MHz-1610MHzGPS, 1420MHz, 2.4GHz/5.8 GHz image mission and other frequencies. This antenna can be used. Process: The material of this antenna FR4-PCB adopts a spiral equiangular gradient form, and the feed line uses a gradient line for impedance matching to achieve ultra-wideband purposes. Specifications: Working bandwidth: 510MHz-10GHz Polarization: Circular polarization right/left Gain: 3dBi-6dBi Impedance: 50 ohms VSWR: Less than 2.4 Size: Helix diameter is 10, excluding connectors Due to different batches, there may be differences in product appearance and printed text, which will not affect use Colour: Black Material: PCB Package Contents: 1 x Helical Antenna Only 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. The measurement allowed error is +/- 1-3cm.
