Want to improve your GPS antenna multipath convergence time performance to near survey-grade GNSS levels? Just using this simple steel plate effectively improves simple patch antenna performance to near professional level antenna setups.
The steel disc provides a ground plane for a low cost patch antenna (such as the u-blox ANN-MB-00) that when coupled with the u-blox NEO-M8P or ZED-F9x receiver allows for centimeter-level positioning. This plate is not needed with larger L1/L2 antennas that have a plane incorporated in their design.
The ⅛” thick steel plate has been tapped to fit 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 magnetic mounted antenna to sit flat on the ground plane while mounted to a tripod.
