The
Tuner
Genius
XL™
(TGXL™)
is
a
2000W
automatic
antenna
tuner
with
full
frequency
coverage
from
1.8
MHz
to
54
MHz.
It
is
designed
to
match
an
antenna
system
with
an
SWR
of
up
to
10:1
automatically.
The
tuner
is
built
to
"broadcast
industry"
commercial
standards
with
a
1500W
100%
Intermittent
Commercial
and
Amateur
Service
(ICAS)
power
rating.
The
absolute
maximum
peal
power
handling
capability
is
2000W.
All
Tuner
Genius
XL
functions
are
controlled
either
from
the
front
panel
of
the
tuner
or
from
a
Windows
computer
software
application.
Using
the
Windows
application
allows
the
TGXL
to
be
installed
away
from
your
operating
position
or
in
another
geographic
location
over
the
Internet.
Additionally,
high
‐
precision
peak
responding
RF
power
and
SWR
meter
displays
are
provided,
eliminating
the
need
for
a
separate
Power/SWR
meter
device
in
your
shack.
The
Tuner
Genius
XL
is
tightly
integrated
with
the
Power
Genius
XL™
(PGXL™)
RF
amplifier
and
all
FLEX
‐
6000™
series
HF
transceivers.
Integration
is
achieved
using
a
standard
LAN
‐
based
API
and
communications
protocol.
The
API
is
published
so
you
can
write
software
applications
for
your
tuner.
The
Tuner
Genius
XL
is
compatible
with
any
modern
HF
radio
on
the
market
today.
When
used
in
conjunction
with
a
Power
Genius
XL
and
a
FLEX
‐
6600
or
FLEX
‐
6700
transceiver,
you
have
a
competitive,
fully
functional
SO2R
(single
operator,
two
‐
radio)
radiosport
station.
In
addition,
support
for
SmartLink
and
multiFLEX™
operation
provides
frustration
‐
free
multi
‐
client
remote
operation.
3 What is an Antenna Tuner?
An
antenna
tuner
is
a
device
in
the
RF
signal
path
between
the
transmitter
(or
transmitter
+
amplifier)
and
its
antenna
to
improve
power
transfer
between
them
by
transforming
the
impedance
presented
at
the
transmitter's
antenna
feed
output
to
a
compatible
value.
This
impedance
change
protects
the
transmitter
from
the
potentially
damaging
effects
of
high
reflected
power,
allowing
the
transmitter
to
avoid
reducing
(folding
back)
power
to
protect
itself.
An
antenna
tuner
is
especially
useful
when
the
antenna
and
feedline
impedance
is
unknown
and
complex.
It's
important
to
understand
that
the
tuner
does
not
change
the
actual
SWR
of
the
antenna
and
feedline.
Instead,
it
transforms
the
impedance
presented
to
the
transmitter.
