Compatibility with New Spektrum remote receivers

  • I will be purchasing a Mercury Power box with GPS for a new project. I will be using a Spektrum DX20 transmitter. I understand that i can connect 4 remote Spektrum receivers to operate with my transmitter. I see on the Horizon Hobby Site the DMSX remote receiver changed and there is only one antenna lead on the new device. It is part Horizon Hobby number SPM9745. The old one is no longer available.

    Is if there is any known compatibility issuers with the new receiver and the Mercury Power box?
