Antenna Connection (option)
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: 25 W
Quality: Able to withstand marine environment
Any 50 ohm coaxial cable heavier than 5D-2V or RG58C/U may be used for the connection between the antenna and
the transceiver unit. Make sure to leave some slack in the cable loop behind the transceiver for service and
maintenance ease.
Lay the antenna, and then solder the M-type connector onto the cable end as shown on page 7.
