CONNECTIONS AND INSTALLATION
■
Antenna
Most stations operate with a whip or long wire (insu-
lated backstay) antenna. However, these antennas
cannot be connected directly to the transceiver since
their impedance may not be matched with the trans-
ceiver antenna connector.
With a 50
Ω
matched antenna all marine bands can-
not be used. The following antenna matcher or an-
tenna tuner may be helpful for antenna installation.
D
Non-Icom tuner
Some non-Icom tuners may be used with the IC-M.
Please consult your dealer or marina if you wish to
connect one. The following internal settings may be
required for connection.
