Appendix S: ORBCOMM Datalink Antenna Coupler Installation

The ORBCOMM Datalink installation can also be done using a shared antenna for both VHF voice
communications and Datalink, using the Avidyne DC50 antenna coupler, part number 700-00015-000.
The Datalink Coupler is a Radio Frequency (RF) device that allows two transceivers (a VHF
communications radio and a Datalink radio) to share a single wide-band VHF antenna. The coupler
contains filters that allow the signals intended for the comm to reach the VHF comm port, while routing
the ORBCOMM Datalink frequencies to the ORBCOMM datalink port.
For information on installing the 700-00015-000 antenna coupler, see the DC50 installation manual,
(document 600-00082-000, Antenna Combiner Installation Manual), available from Avidyne.
The DC50 Datalink Coupler is not for MLX770 Iridium Datalink Transceiver installations.
