@ INSTALLATION
The Mirage B-34 may be placed in a convenient operating position.
There must be adequate ventilation for the finned heat-sink.
This generally means at least 1 inch clearance from the heat-sink to
any surrounding enclosure and an unobstructed flow form the front to
back of the heat-sink.
Do not operate the amplifier in places where it will be exposed to the
direct rays of sun or a nearby heat source such as heaters,
radiators, etc.
B CAUTION : with extended use the heat-sink becomes very hot.

Wiring and Operation
Ifit
is
necessary
to
extend
the
DC
power
leads
use
wire
of
the
same
gauge
in
order
to
avoid
a
voltage
drop
on
your
power
leads.
Be
careful
that
the
DC
power
supplied
is
no
higher
than
15
volts
of
damage
may
result.
A
source
voltage
of
13.8
volts
is
recommended
and
should
be
used
whenever
available.
Some
automobiles
will
generate
a
high
current
surge
when
started.
Itis
recommended
that
the
amplifier
be
place
in
the
off
position
when
starting
your
vehicle.
Use
a
minimum
length of
good
quality
50
ohm
cable
between
the
radio
and
the
amplifier.
The
antenna
system
should
have
a
VSWR
of
1.5:1
or
better
for
the
best
performance.
If
used
in
a
mobile
installation,
choose
a
good
mobile
antenna
which
will
withstand
the
power
of
this
amplifier.
Be
sure
to
check
the
SWR
for
any
degrading
once
the
antenna
has
been
heated
by
a
few
minutes
of
operation.
An
antenna
with
a
rating
of
100
waits
is
recommended.
