Note : if outdoor walls contain much metal ( such as reinforcing bar, shielded network, etc. ), which absorbs relatively more signals, bracing frames shall be used to fix antennas, leaving a certain distance among antennas and walls in order to reduce signal absorption

注意：如果外墻壁中含金屬（如鋼筋，屏蔽網等）較多，其對信號的吸收較多，請使用支撐架將天線固定，使天線與墻壁有一定距離，以減少對信號的吸收。
