Connecting GNSS (GPS) and VHF antennas

Your radio requires a VHF antenna to function as a radio. If you intend to use the radio’s internal GNSS (GPS) receiver then you will also require a GNSS (GPS) passive antenna to be connected. The antenna connections can be protected so that they cannot come into contact with any grounded bare metal. This is especially important when installing the radio on metal structure.

Pre-requisites:

  • Ensure you have installed your antennas in accordance with the instructions supplied with the antennas.

  • Ensure the cables have been properly routed to the Base station and that sufficient cable length is available to make the connections.

Note

  • Follow steps 2 and 3 to install the antennas with no protection.

  • When mounting the Base station on metal structure, in order to prevent galvanic corrosion, ensure ALL steps are followed so that the antennas are isolated from the vessel’s metalwork.

  1. Feed the supplied heat shrink tubes over the connector ends of your antennas.
  2. Plug the antenna connectors into the relevant antenna connections on the Base station.
  3. Secure by tightening the locking collars.
  4. Pull the heat shrink tubes down over the antenna connector, ensuring the connectors are fully covered.
  5. Apply heat evenly over the heat shrink tubes until they are shrunk uniformly and resemble the shape of the connectors.
