SETUP AND CONNECTIONS
ANTENNA SELECT FUNCTION:“Auto” Once an antenna has been selected for use with a
band by pushing [ANT], the antenna is automatically
selected whenever that band is accessed.
[EXAMPLE]: a 3.5/7 MHz antenna is connected to
[ANT1], a 21/28/50 MHz antenna is connected to
[ANT2]. When the antenna selector function is set to
“Auto,” an antenna is automatically selected when
changing bands.
When “Manual” is selected, you can use the
[ANT1]/[ANT2] switches, however, band memory
does not function. In this case you must select an an-
tenna manually. However, the 144 MHz antenna will
still be selected automatically.
[EXAMPLE]: an optional external antenna tuner and
HF antenna are connected to [ANT1] and a 50 MHz
antenna is connected to [ANT2].
ANTENNA SELECT FUNCTION:“Manual”
ANTENNA SELECT FUNCTION:“OFF”
In this case, only [ANT1] and the 144 MHz antenna
connector can be used. [ANT] does not function.
The IC-746 has 2 antenna connectors for the HF/50
MHz bands, [ANT1] and [ANT2], and 1 antenna con-
nector for the 144 MHz band; a total of 3 antenna con-
nectors.
For each operating band the IC-746 covers, there is a
band memory which can memorize a selected an-
tenna. When you change the operating frequency be-
yond a band, the previously used antenna is
automatically selected (see below) for the new band.
This function is convenient when you use more than 1
antenna.
