(Navimow X4) Do I need to use a Signal Enhancement Antenna?

Signal Enhancement Antenna is mainly used to address insufficient wireless communication distance in front yards, backyards, or large areas. If only a Primary Antenna is used, the communication distance is typically within 200 meters. If any area of the lawn is more than 200 meters away from the Primary Antenna, a Signal Enhancement Antenna is required to ensure stable communication(sold separately).
