  • This product is developed specifically for 2.4 GHz and 5.8 GHz frequency bands. 2.4G is compliant with the IEEE 802.11B/G/N standard and 5.8 is a bidirectional power amplifier that complies with the IEEE 802.11A/N standard. The product matches frequency spread techniques such as direct sequence (DSSS) and orthogonal frequency division multiplexing (OFDM). Using TIME DIVISION DUPLEX (TDD) fast microwave detection technology and linear power amplifier technology, it greatly expands the wireless RF communication distance while keeping the transmission rate of 802.11B/G/N wireless devices unchanged.

  • ATTENTION: Please pay attention before you place an order. You need to disassemble the original remote and remove the original antenna before you install the cable. In theory, although the installation process is non-destructive installation. However, you still have the risk of damaging the original remote control and losing the warranty for the remote control or drone. And users need to be careful that the outer insulation layer and shielding metal layer of the coaxial cable are intact.
  • Before installation, please watch the video teaching carefully to ensure the correct installation of the cable. Be careful to use the tool to ensure that the cable is not broken, twisted, or damaged. We do not recommend this cable to be installed repeatedly. Only one pair of cables is included in this package. It will include any tools for retrofitting.  Once the antenna wrap and, install package opened, no returns are offered when you are doing the install yourself.  A guarantee against any defects would still be covered for a replacement of bad part or antenna.
  • Please note that the DJI smart controller, Mavic 3, Mavic Air 2 controller and the Mavic mini 2 controller all require professional install UNLESS you're out of the USA. This is due to the difficulty of the mod to these remotes.
