9 ANTENNA TUNER OPERATION ■ Antenna connection and selection The IC-7410 has 2 antenna connectors for the HF/50 MHz bands, [ANT1] and [ANT2]. You can memorize the antenna for each operating band the IC-7410 covers. When you change the operating band, the previously set antenna connector for that band is automatically selected. (See below) This function is especially convenient when you use 2 antennas for HF and 50 MHz band operation. [ANT•METER] To use the band memory, set the "[ANT] Switch" item to "Auto" in the Set mode. (p. 87) • Antenna selection mode: "Auto" (default) Once an antenna has been selected for use with a band by pushing [ANT•METER], the antenna is automatically selected whenever that band is accessed.

[ANT•METER]
The IC-7410 has 2 antenna connectors for the HF/50
MHz bands, [ANT1] and [ANT2].
You can memorize the antenna for each operating
band the IC-7410 covers.
When you change the operating band, the previously
set antenna connector for that band is automatically
selected. (See below)
This function is especially convenient when you use 2
antennas for HF and 50 MHz band operation.
To use the band memory, set the “[ANT] Switch” item
to “Auto” in the Set mode. (p. 87)
• Antenna selection mode: “Auto”
(default)
Once an antenna has been selected for use with a
band by pushing [ANT•METER], the antenna is auto
-
matically 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,” the correct antenna is automatically selected
when you changes bands.
• Antenna selection mode: “Manual”
[ANT•METER] functions, however, the band memory
function is disabled. In this case, you must select an
antenna manually.
[EXAMPLE]:
an optional antenna tuner and HF an-
tenna are connected to [ANT1] and a 50 MHz an-
tenna is connected to [ANT2].
• Antenna selection mode: “OFF”
[ANT•METER] does not function. The [ANT1] con
-
nector is always selected for HF and 50 MHz bands
operation.
