4.2.2. SWR2Air mode [AA-200 only]
RigExpert AA-200 Antenna Analyzer presents the new
SWR2Air
mode which is
designed to help in adjusting antennas connected via long cables.
Traditionally, this job requires at least two persons: one of them adjusts certain
adjustment elements of the antenna, while the other one continuously watches the value
of the SWR on the lower end of the cable and corrects actions of the first person.
There is a way to do the same job in a much more simple way by using the
SWR2Air
mode. The result of SWR measurement is transmitted on the specified frequency where
it can be heard with a portable HF or VHF FM radio. The length of audio signal
coming from the loudspeaker depends on the value of measured SWR.
The
SWR2Air
mode is activated by pressing the
F
+
OK
combination in the
SWR
measurement
screen.
F
+
2
allows setting the frequency to tune the receiver to.
4.2.3. MultiSWR mode
RigExpert AA-200/AA-500 Antenna Analyzers have a unique ability to display SWR
at up to five different frequencies at a time.
