EXTERNAL ANTENNA
If the installation of an external antenna is required, proceed as follows:
• remove the internal antenna, made of an 8 cm long folded wire, from the
ANT input (fi g.3).
• Connect the centre core of the coaxial cable of the antenna to the ANT
input (fi g.4). The metallic shield must be connected to the SHIELD input.
• Coaxial cable during laying must not be throttled and bended at a right
angle. Must also be taken away from heat sources.
• The antenna must be installed vertically at a distance of at least 1 metre
above the boat fl oating level, away from electrical sources of disturbance
and not inside any metal structures.
• Do not install the antenna close to that of other equipment as VHF, radar,
GPS, etc.
