in
areas subject to extr-eme heat, cold, or vibrations,
or near
TV
sets,
radios
and electro-magnetic
sources.
For mobile

MOBILE
MOUNTING BRACKET
is
available..
Select
a
location
which can support the weight of the
transceiver
and
does
not
interfere
with the operation of the
vehicle.
•ADJUSTABLE ANGLES

stand
on
the
bottom
of the IC-725
gives
the
transceiver
two
selectable angles.
Select
an antenna, such
as a
well-matched
50
12
antenna
and
feedline.
The
transmission
line
should be
a
coaxial
cable.

should be
less
than
1.5:1.

the distance
between
the
GROUND
terminal
and ground
as
short
as
possible.
