Sparkfun GNSS Multi-Band L1/L2/L5 Surveying Antenna - TNC (SPK6618H)

The SPK6618H is a certified GNSS/GPS surveying antenna capable of tri-band (L1/L2/L5) reception for GPS, GLONASS, Galileo, and BeiDou constellations. These 'UFO' antennas offer exceptional performance for their price. The antenna features a built-in ground plane with significant filtering and amplification of L1, L2, and L5 frequencies across all major satellite constellations, making it ideal for surveying or fixed antenna applications.This antenna is perfect for applications that require high precision and reliability. Whether you're working on a large-scale land survey, setting up a permanent GNSS reference station, or conducting geodetic research, the SPK6618H provides the accuracy and consistency you need. Its robust design ensures optimal performance even in challenging environments.Designed for the latest triband GNSS receivers, this antenna offers a fast, easy, and reliable multi-band solution. It can also be used with any GPS/GNSS receiver that benefits from L1/L2 dual or L1/L2/L5 triband reception. While it significantly enhances performance, ensure your receiver supports L1 and L2 signals to fully utilize this antenna's capabilities. Compatibility with L5 is optional, and using this triband antenna will not harm your receiver if L5 is not supported.The antenna incorporates a 13 cm ground plane with six hybrid couplers to achieve signal phasing, making it less sensitive to manufacturing inconsistencies. This design innovation ensures superior performance and reliability.Certified by the National Geodetic Survey, the SPK6618H's ANTEX and ANTINFO files are available, and it is listed under SFESPK6618H on the NGS Antenna Calibrations website. This certification underscores its precision and reliability for professional surveying tasks.The antenna features a TNC female connector, commonly found on surveying antennas. For compatibility with GNSS receivers, a TNC Male to SMA adapter or cable is recommended. The standard 5/8"-11TPI connector is used for mounting, which is not compatible with camera tripods. A 5/8" to 1/4" tripod adapter is recommended for mounting purposes. Additionally, 5/8"-11TPI threaded rods are readily available in most hardware stores in North America. For permanent installations, refer to the tutorial on building a DIY GNSS reference station.Note: A GNSS receiver and interface cables are not included with the antenna and must be purchased separately.Features:
