GPS Antenna Ground Plate

Added to your shopping cart

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 that when coupled with the Ublox GPS-RTK NEO-M8P receiver allows for centimeter-level positioning.

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 GPS Magnetic Mount Antenna to sit flat on the ground plane while mounted to a tripod.

  • Diameter -- 4 Inches
  • Thickness -- 1/8"
  • Weight -- 0.4211 lbs
  • Center Thread -- 1/4-20 UNC Thread
  • Finish -- Industrial
