![]() ![]() Installation with the rear baggage deck cover removed. Perpendicular to the oval slot provided the strongest signal. Microstrip antenna positioned on the GTX345R. White Wi-Fi antenna (probably blends best with interior)ĩ dBi (slightly higher gain, but probably not material).I re-purposed a whip antenna with integrated extension cable ( link), but that antenna is discontinued and the RF cable is too long anyway. Just ensure that the connectors mate correctly. The following parts list is a good starting point, but alternatives should also work fine. The latter is necessary to route an RF cable behind the shelf support. The only required tools are a #2 Phillips screwdriver to remove the baggage deck cover, and a 3mm hex driver to remove one shelf support screw. Bluetooth uses the same frequencies as low-band Wi-Fi (2.4 GHz), which simplifies finding parts. This solution re-broadcasts the GTX345R output beyond the carbon fiber cocoon. It is remarkable that any Bluetooth signal reaches the front seats. Which is fantastic for weight, but blocks RF, leaving only small "transparent" gaps around the perimeter of the shell. The entire rear shell, flange and deck cover of the extended baggage compartment rests directly on top of the GTX345R. ![]() The transmitter is under the GARMIN label on the GTX345R, as shown by the black oval added with a Sharpie: The GTX345R location in the DA40 is almost diabolically designed to prevent Bluetooth reception. The total cost is ~$30, is passive, requires no permanent change to the airframe, while providing excellent connectivity - even with two people and lots of luggage in the back! One of my close friends happens to be a professional RF guru, and helped find a simple solution to the GTX345R Bluetooth problem in the DA40. ![]()
