    FrSky Tandem Dual Frequency Transmitters

    Would this System technically work using 2.4Ghz alone when sub is submerged? I would need to depend on the RX antenna protruding above the water when sub is submerged. Is there a way to extend the 2.4Ghz with RG178? Do the RX's have IPEX connectors? Just been on my mind, hope this makes sense? I would like to employ this system for it's many capabilities.

          Yes, but that's not a tandem receiver

                  Instead of an ipex connector how about installing a male- female connector on the tip existing antennae?

                  SMA Male Connector Crimp/Solder Attachment for RG178
                  https://www.l-com.com/sma-male-connector-crimp-solder-attachment-rg178-lccn3025
                  L-com’s SMA male connector for RG178 coax uses a crimp/solder attachment method. This SMA connector is one of the many RF coaxial connectors in L-com’s product line up and like all our products, they will ship the same day. Our SMA male connector operates up to a maximum frequency of 1 GHz.&&The specifications and a basic dimensional drawing for LCCN3025 male SMA connector can be found in this datasheet PDF.


                  SMA Female Connector Crimp/Solder Attachment for RG178

                  L-com’s SMA female connector for RG178 coax uses a crimp/solder attachment method. This SMA connector is one of the many RF coaxial connectors in L-com’s product line up and like all our products, they will ship the same day. Our SMA female connector operates up to a maximum frequency of 2 GHz.&&The specifications and a basic dimensional drawing for LCCN3022 female SMA connector can be found in this datasheet PDF.


                  Would also make servicing the wtc easier.
