MG21 Internal Antenna Datasheet

The internal antenna on the MG21 are enclosed inside for a sleek look while maintaining excellent performance. When in use the internal antenna has a bias towards the front face. The dipole shape of coverage the antennas generally excel at allowing users to place the MG in areas where a directional patch antenna cannot be mounted. A benefit of the internal antenna is the smaller footprint where it will be mounted.
