BT2S Module Datasheet 6 ANTENNA INFORMATION 6 Antenna Information 6.1 Antenna Type BT2S uses an onboard PCB antenna. 6.2 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 BT2S is inserted to the PCB, sufficient space needs to be reserved for the antenna.
