5 Antenna Information
5.1 Antenna Type
BT7L uses an onboard PCB antenna.
5.2 Antenna Interference Reduction
To ensure optimal RF performance, it is recommended that the antenna be at least 15 mm
away from other metal parts. If metal materials are wrapped around the antenna, the
wireless signals will be reduced greatly, deteriorating the RF performance. Because BT7L
is inserted to the PCB, sufficient space needs to be reserved for the antenna.
