Main Features:<br />1. Custom made 2.4G radio signal amplifier・ especially designed for long range application like FPV.<br />2. High speed receiving and transmitting auto-switching circuit・ can switching between receiving and transmitting modes automatically.<br />3. With the increasing on-board wireless electronic devices like FPV application・ the interference between different devices also getting more and more severe・ and the radio system range and reliability also greatly affected・ this amplifier is just designed to increase the range and reliability of your radio system.<br />4. The module requires 3.7 - 5.5V power supply・ higher than this voltage range may damage the module permanently and NOT covered by warranty.<br />5. When use BEC unit as power supply・ only high quality BEC can be used otherwise it may introduce interference to the system.<br /><br />Receiving gain: 10dB<br />Transmitting gain: 11dB<br />Receiving figure: Less than 3.0dB・<br />Input power range: 4dBm - 20dBm<br />Peak power: 33dBm; 2W (input power plus amplifier power)<br />Power supply: 3.7-5.5V (High quality UBEC is needed when using a BEC module as power supply)<br />Antenna gain: 6DBI<br /><br />    Specifications<br />Specifications<br />	 Type: Spare Set・ Antenna                                                	<br />Dimension and Weight<br />	 Package Weight: 0.08 kg                                                  <br />                        Package Size (L x W x H): 20.5 x 6 x 2 cm / 8.06 x 2.36 x 0.79 inches                                                	<br />Package Contents<br />	 Package Contents: 1 x Amplifier Module・ 1 x Antenna Adaptor・ 1 x Antenna                                                	<br /><br /><br /><br />                                                                   Product Safety Disclaimer: <br />We do not accept any responsibility or liability for misuse of this or any other product.
