5.2 Preparing for installation
No special tools or equipment are required for installation.
5.2.1 Coast Station location
The Coast Station is designed for installation in a protected environment, i.e. indoors or inside a fully
weather-proof enclosure. The Coast Station must not be installed in a location where it may be exposed to rain
or spray.
5.2.2 VHF antenna and cable
The VHF antenna should have the following specification:
● Centre frequency 159MHz
● VSWR < 2.0
● Impedance 50 Ohms
● Power handling 12.5 Watts
● Gain 3dBi or 6dBi
It is recommended that high quality RG213 or RG214 co-axial cable is used to connect the VHF antenna to the
transceiver. The antenna cable should be as short as possible and no more than 30 metres (100 feet) in length.
When selecting the installation location for the VHF antenna:
● Install the antenna as high as possible.
● Keep the antenna away from any large vertical metallic structures.
Install the antenna with at least 1 metre horizontal separation from any other VHF antenna mounted at the
same level.
5.2.3 GPS antenna and cable
The supplied GPS antenna should be used and located externally with a clear view of the sky. Installation of
the GPS antenna is required to enable the data logging feature of the Coast Station.
5.2.4 Power supply
The Coast Station should be connected to a mains supply using the supplied mains adaptor with the
appropriate international plug type attached.
The performance and reliability of the VHF antenna is essential to correct operation of the
transceiver. Ensure that a high quality antenna suitable for use in the appropriate
environmental conditions is selected. Ensure all co-axial connections are well made and
!
The VHF antenna should be installed according to the manufacturer's instructions.
!
The VHF antenna must be installed with at least 1 metre horizontal separation from any other
VHF antenna mounted at the same level.
!
If at any time during installation or use of the Coast Station there is a requirement to perform
a ‘power reset’ it is important that both the power supply adaptor and the USB connector are
removed from the Coast Station as the USB connection can provide power to some parts of
the Coast Station. When re-applying power the power adaptor should be connected first
followed by the USB connector if required.
