VHF antenna connector 
The VHF antenna connector is a female 'N' type co-axial connector. The antenna ground is galvanically
isolated from the AIS AtoN system ground. The connector and mating half must be sealed with self
amalgamating tape once mated. A lightning protector may be installed in line with the VHF antenna connector.
The recommended lightning protector is Huber+Suhner part number 3401.17.C with gas discharge tube
9071.99.0547. See section 5.6 for further information.
5.4.5
GNSS antenna connector 
The GNSS antenna connector is a female 'TNC' co-axial connector. The connector and mating half must be
sealed with self amalgamating tape once mated.
Refer to section 5.7 for further detail on the selection and installation of an external GNSS antenna. If the
External GNSS antenna connector is not used it must be protected with the supplied blanking cap.
5.4.6
Earth connection stud 
The earth connection stud is an M4 stud connected to the VHF antenna ground. This point should be connected
to a common grounding point for lightning protection. 
5.5 Connecting power
The transceiver requires a nominal 12VDC or 24VDC supply and will operate between 10V and 32VDC. The
peak current drawn when operating from 12VDC is 3A and when operating from 24VDC is 2.5A. Power should
be connected using the supplied interface connector and cable. It is recommended that 5A rated fuses are
installed in line with the power supply positive and negative connections.
