2-3-5. Antenna Connection
Provide a location as high and clear as possible, free from the influence of nearby antenna, rigging and
masts.
However, any good quality antenna, complying with the following requirements, may be arranged locally.
A high-gain antenna is preferable. If you are not sure, consult with your dealer.
• Frequency range: 155 MHz to 164 MHz
• Impedance: 50 ohms
• Polarization: Vertical
• Input power: 30 W
• Quality: Able to withstand marine environment
Any 50 ohm coaxial cable heavier than 5D-2V (equivalent to RG-212/U) may be used for the connection
between the antenna and the transceiver. To extend the antenna cable longer than 20 m, use heavier
coaxial cable, such as 8D-2V or RG-213/U, to minimize power loss and signal attenuation through the
cable. Make sure to leave some slack in the cable loop behind the transceiver for service and
maintenance ease.
