13 ANTENNA TUNER OPERATION ■ Antenna connection and selection The IC-9100 has 2 antenna connectors for the HF/50 MHz bands, [ANT1] and [ANT2], and a dedicated antenna connector for each of the 144 MHz, 430 MHz and 1200 MHz* bands; a total of 5 antenna connectors. You can memorize the antenna for each operating band the IC-9100 covers. When you change the operating band to one outside of the current memorized antenna band, the antenna is automatically selected for the new band. (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, select "Auto" as the "[ANT] Switch" option in the Set mode. (p. 163) • 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. [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. 3.5/7 MHz 21/28/50 MHz 144 MHz 430 MHz 1200 MHz bands bands band band band* [ANT1] [ANT2] [144MHz ANT] [430MHz ANT] • Antenna selection mode: "Manual" [ANT•METER] functions, however, the band memory function is disabled. In this case, you must select an antenna manually. • T he antenna connectors for the 144 MHz, 430 MHz and 1200 MHz* bands are automatically selected.

[ANT•METER]
The IC-9100 has 2 antenna connectors for the HF/50
MHz bands, [ANT1] and [ANT2], and a dedicated an-
tenna connector for each of the 144 MHz, 430 MHz
and 1200 MHz* bands; a total of 5 antenna connec
-
tors.
You can memorize the antenna for each operating
band the IC-9100 covers.
When you change the operating band to one outside of
the current memorized antenna band, the antenna is
automatically selected for the new band. (See below)
This function is especially convenient when you use 2
antennas for HF and 50 MHz band operation.
To use the band memory, select “Auto” as the “[ANT]
Switch” option in the Set mode. (p. 163)
• 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.
• The antenna connectors for the 144 MHz, 430 MHz and
1200 MHz* bands are automatically selected.
[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] connec
-
tor is always selected during HF and 50 MHz bands
operation.
