{"product_id":"gps-antenna-ground-plate-1","title":"GPS Antenna Ground Plate","description":"\u003cp\u003eThis plate significantly increases the performance of GPS and GNSS antennas.\u003c\/p\u003e\n\u003cp\u003eMany magnetic mount GPS antennas rely on being mounted on a car or other large metallic object to provide a good ground plane. But what if you want to use an antenna not on a car? The GPS Antenna Ground Plate is the solution!\u003c\/p\u003e\n\u003cp\u003eWe're always trying to improve things here at SparkFun. This updated design features a 1\/4-20 UNC nut welded to the bottom of a thinner plate (1\/8\" is now 1\/16\"). The nut adds additional thickness so now the tripod screw is no longer prone to the plate. We've also decreased the thickness of the plate to reduce weight.\u003c\/p\u003e\n\u003cp\u003eThe steel disc provides a ground plane for a low cost u-blox ANN-MB-00 antenna and enables centimeter-level positioning when coupled with a L1\/L2 capable GNSS receiver such as the ZED-F9P.\u003c\/p\u003e\n\u003cp\u003eThe 1\/16” thick steel plate fits onto the standard ¼-20 UNC camera mounting screw. While it is not the cleanest piece of steel and weighs in at a hefty 0.4211 lbs, it does provide a solid base to allow a GPS Magnetic Mount Antenna to sit flat on the ground plane while mounted to a tripod.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 Inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/16\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4211 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Thread\u003c\/strong\u003e: 1\/4-20 UNC Thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Industrial\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/0\/c\/0\/1\/c\/AntennasForRTK_WhitePaper__UBX-16010559_.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eu-blox white paper on using low cost antennas for RTK\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":32390989611091,"sku":"GPS-17519","price":8.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/17519-GPS_Antenna_Ground_Plate-01.jpg?v=1612431589","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/gps-antenna-ground-plate-1","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
