{"title":"MAN1216Q50 Multi-Band GNSS Helical Antenna - Locking SMA","handle":"gnss-multi-band-l1-l2-l5-helical-antenna-locking-sma","url":"/products/gnss-multi-band-l1-l2-l5-helical-antenna-locking-sma","description":"The MAN1216Q50 is the locking version of SparkFun’s multi-band GNSS helical antenna, designed for high-precision L1/L2/L5 reception in compact equipment mounts. It adds a specialised three-screw flange at the base so the antenna can be permanently installed while still connecting via any SMA cable.The locking flange is useful in high-vibration applications such as UAVs, autonomous agricultural rovers and automotive equipment, where a standard threaded SMA connection may loosen over time. The extra mounting points help secure the antenna to the enclosure and reduce stress on the SMA connector.Internally, the antenna uses a Quadrifilar Helix structure for strong gain and wide-angle circular polarisation, helping with reception from low-elevation satellites even when the antenna is tilted or manoeuvring. It covers GPS, GLONASS, BeiDou, Galileo and L-Band signals.This antenna can be used with an L1-only receiver, but to get the full benefit you will need a receiver capable of L1/L2 or L1/L2/L5 reception.Features:Locking flange: Three-screw base for permanent mounting.Security: The three screw points physically secure the antenna to the case, preventing it from loosening under vibration or movement.Durability: The additional mount points transfer horizontal torsion and physical shock away from the sensitive SMA connector and into the stronger surrounding chassis materials.Multi-band GNSS: Supports GPS, GLONASS, BeiDou, Galileo and L-Band coverage.Quadrifilar Helix: Provides excellent gain and wide-angle circular polarisation.Low-profile design: Maintains a lower profile than many other helical options.SMA compatible: Can be used with any SMA cable.Specifications:GPS: L1, L2, L5GLONASS: G1, G2Beidou: B1, B2a, B2b, B3iGalileo: E1, E5a, E5b, E6L-Band: L-BandGain: 28dBNoise Figure Typical: 1.5dBNoise Figure Max: 2dBVoltage: 3.0-16VCurrent: 15-20mAOverall Antenna Weight: 25gDimensions: 50mm x 50mm x 42.16mmIP67 Compliance: IP67 ComplianceA compact choice for GNSS projects where multi-band reception and a mechanically secure antenna mount are both important.","vendor":"SparkFun","product_type":"GNSS Antenna","in_stock":true,"options":[],"variants":[{"id":16181,"title":"Default Title","sku":"SF-GPS-30249","mpn":"GPS-30249","price":196.6,"on_sale":false,"in_stock":true,"available_quantity":173}]}
