The IC-7700 has 4 antenna connectors for the
HF/50 MHz bands, [ANT1], [ANT2], [ANT3], and
[ANT4].
For each operating band the IC-7700 covers, there is a
band memory which memorizes the selected antenna.
When you change the operating frequency outside of a
band, the previously used antenna is automatically se-
lected (see below) for the new band. This function al-
lows automatic switching of 4 separate antennas for
HF and 50 MHz bands operation.
After an antenna has been selected for use (by push-
ing [ANT]
), the antenna is automatically selected
(MF1)
whenever that band is used.
[EXAMPLE]: a 3.5/7 MHz antenna is connected to
[ANT1], a 21/28 MHz antenna is connected to [ANT2],
a 50 MHz antenna is connected to [ANT3]. When the
antenna selector function is set to "Auto," an antenna
is automatically selected when changing bands.
A receive-only antenna can be specified for [ANT4].
When "Manual" is selected, you can use the all an-
tenna connectors, [ANT1] [ANT2], [ANT3] and [ANT4],
however, band memory does not function. In this case
you must select an antenna manually.
In this case, only [ANT1] antenna connector can be
used. [ANT]
