8.1.3.2 VHF Antenna<br />
When individual GPS antenna is used, the additional VHF antenna must also be<br />
connected<br />
For detailed description of this antenna, see Chapter 14 Outline Drawings<br />
Location of the m<strong>and</strong>atory <strong>AIS</strong> VHF-antenna should be carefully considered. Digital<br />
communication is more sensitive than analogue/voice communication to interference<br />
created by reflections in obstructions like masts <strong>and</strong> booms. It may be necessary to<br />
relocate the VHF radiotelephone antenna to minimize interference effects.<br />
Install the VHF antenna referring to drawings in beginning of this chapter<br />
The antenna should be connected using RG214 cable or better using the connectors<br />
in the “Plug Kit” which is delivered with the units.<br />
Calculation of cable length/attenuation etc is described in chapter 8.2<br />
