Increasing Bluetooth Range
The internal bluetooth module uses a self-adhesive dipole antenna, fixed to the inside of the product.
This antenna uses a standard U.FL connector, which may be removed, and replaced with an external
antenna, by means of a 10cm U.FL to bulkhead SMA cable.
When disassembling the case, a small plastic ‘blanking plate’ may be removed, to open up the hole
through which to secure the SMA connector.
For the antenna, the FatShark 2.4GHz dipole works well:

And for the required cable, U.FL to SMA:

Note: ImmersionRC will be supplying a kit with the required antenna and cable in the near future, but in the
interest of speed to market, the above combination will work well.
