[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”
