The default delivery is a right-handed antenna with an SMA female male-threaded female connector. Ultra-Wideband 942MHz-6.5GHz Helical Antenna This antenna is an ultra-wideband Archimedean spiral antenna available in both left-hand and right-hand circular polarization. It can be used for direction finding, spectrum analysis, signal analysis, navigation positioning, broadband measurement, and direction finding. It provides 5-7dBi of circularly polarized directional gain in the 942MHz-6.5GHz frequency band. It features low standing waves, high gain, and outstanding performance. Typical operating frequencies include: 915MHz, 1090MHz ADS-B, 1268MHz-1610MHz GPS, 1420MHz, and 2.4GHz/5.8GHz image transmission. Craftsmanship: This antenna is made of FR4-PCB with a spiral equiangular gradient pattern. The feed line uses a gradient line for impedance matching to achieve ultra-wideband performance. Operating Bandwidth: 942MHz-6.5GHz Polarization: Circularly polarized, right-handed Ratio:Less than 1.5dB (typical) Radiation Angle: H=E=70° Gain: 5dBi-7dBi Impedance: 50 ohms Standing Wave Ratio:Less than 2.4 (typical) Dimensions: Helical diameter 10mm, height 63mm (including connector) Color:As Shown Material:PCB Package Contents: 1 * ZN35 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.
