Ground Plane Specifications
NOTE: Please note this antenna equires a ground plane (MMG P/N 17-1000-A). The ground
plane should be at least six inches in diameter. See Figure A - 2

Figure A - 2. Ground Plane Specification
If the enclosure for the board is metal and at least 6" across, and the antenna is connected
directly to the enclosure, no ground plane is required, as the enclosure is the ground plane.
The radiation pattern of the recommended antenna is of a traditional dipole (RF pattern as a
donut). The orientation of the antenna should be in the vertical position (straight up or
straight down), such that the RF pattern is omni-directional in the horizontal plane.
