{"title":"TOPGNSS TOP106 L1/L2 GNSS Surveying Antenna - TNC","handle":"gnss-multi-band-l1-l2-surveying-antenna-tnc-top106","url":"/products/gnss-multi-band-l1-l2-surveying-antenna-tnc-top106","description":"The TOP106 from TOPGNSS is a certified GNSS/GPS surveying antenna for receiving L1/L2 bands from GPS, GLONASS, Galileo and BeiDou constellations. It is suited to surveying, handheld and portable GNSS work, as well as fixed antenna installations.Inside, the antenna includes a built-in 130mm ground plane, filtering and amplification for both L1 and L2 frequencies. Its design uses six hybrid couplers for signal phasing, helping make the antenna less sensitive to manufacturing variations such as inconsistent board dielectric.This antenna is designed for modern dual-band GNSS receivers, but can also be used with any GPS/GNSS receiver that can benefit from L1/L2 reception. Check that your receiver supports the L1 and L2 signals output by this antenna.The TOP106 has a female TNC connector commonly found on surveying antennas and uses a standard 5/8\"-11TPI surveying equipment thread. It is not directly compatible with a camera tripod without a suitable 5/8\" to 1/4\" tripod adapter. The antenna has National Geodetic Survey certification, with ANTEX and ANTINFO data available under SFETOP106.Specifications:Gain: ≥5dBiLNA Gain: 40dBReception Frequencies: L1 and L2L1: 1555 to 1615MHzL2: 1198 to 1278MHzAntenna Impedance: 50 OhmOverall antenna weight: 335gBare antenna element weight (including MMCX connector, with RF shield): 160gDimensions: 148 x 55mmWaterproof: IP67Connector: Female TNCAntenna Phase Center L1: 48.0mmAntenna Phase Center L2: 52.9mmAntenna Phase Center Average: 50.45mmUse a TNC male to SMA cable when connecting to many compact GNSS receiver boards, and choose a suitable surveying pole, mount or tripod adapter for installation.","vendor":"SparkFun","product_type":"GNSS Antenna","in_stock":true,"options":[],"variants":[{"id":16171,"title":"Default Title","sku":"SF-GPS-17751","mpn":"GPS-17751","price":393.25,"on_sale":false,"in_stock":true,"available_quantity":52}]}
