The boards are equipped with onboard antennas, with a normal distance of 10-15 meters. If they are installed in a metal shell (which will block the signal) or increase the Bluetooth distance (20-30 meters), external antennas will be used.<br/>2. Customers are required to purchase 2.4G antennas (antenna extension cables, antenna rods) on their own, and this product does not include external antennas.</p><p><strong><span style="font-size:20px">Product List:</span></strong><br/>Set 1:<br/>APTX1 amplifier board * 1</p><p>Set 2:<br/>APTX1 amplifier board * 1<br/>Shell * 1</p><p>Set Three:<br/>APTX1 amplifier board * 1<br/>Lead wire * 5<br/></p></div></div><br/>
