• Description
• Many 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 an antenna not on a car? The GPS Antenna Ground Plate is the solution! This plate significantly increases the performance of GPS and GNSS antennas.
• We'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.
• The 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.
• The 1/16" thick steel plate fits onto the standard 1/4-20 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.
