It can be used for direction finding, spectrum analysis, signal analysis, navigation positioning, broadband measurement, direction finding, etc. It provides 5-7dBi circular polarization directional gain in the frequency band of 942MHz-6.5GHz. Low standing wave, high gain, and performance. The typical working frequencies are: 915MHz, 1090MHzADS-B, 1268MHz-1610M HzGPS, 1420MHz, 2.4GHz/5.8 GHz image transmission. This antenna can be used at other frequencies. 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 the purpose of ultra-wideband. Working bandwidth: 942MHz-6.5GHz Polarization mode: circular polarization right-handed/left-handed ratio: Less than 1.5dB Radiation angle: H=E=70° Gain: 5dBi-7dBi Impedance: 50 ohms Standing wave ratio: Less than 2.4 Size: Spiral diameter is 10, height 63 including connector 942MHz-6.5GHz UWB Ultra-Wideband Coplanar Omnidirectional Antenna Specification:A Left-Handed External Thread Inner Hole Color: Blue Material: Plastic+Metal Package Contents: 1 * 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.
