Product overview
The VLG BDS+GPS dual-mode satellite communication Antenna combines BeiDou satellite transmission and reception with BDS B1 and GPS L1 positioning. It transmits in the L band at 1615.68±4.08MHz using left-hand circular polarization and receives in the S band at 2491.75±4.08MHz using right-hand circular polarization. The B1/L1 positioning bands also use right-hand circular polarization. Applications include satellite communication and positioning for drones and small aircraft, vehicle navigation and location tracking, fishing-boat navigation, outdoor exploration and emergency rescue equipment.
Its compact structure measures Φ104mm*12.8mm, excluding the cable, for installation in space-constrained devices such as vehicles and handheld equipment. The output connection uses a first-generation terminal with a 110mm line length and 1.37 line. Input impedance is 50Ω and VSWR is ≤2.0. BeiDou gain is ≥3.5dBi at the vertex, ≥1dBi at a 70° elevation angle and ≥-3.5dBi at a 20° elevation angle. Vertex gain for B1/L1 is ≥1dBi.
