Requirentents,
The
location
for
radio
equipment
depends
on
the
tactical
situa-
tion
and local
conditions.
Depressions,
valleys,
and
other
lorv
places generally
are
poor
loca-
tions for
radio
reception
because
the
surround-
ing
terrain
absorbs
r-f
energy.
Weak
or Ltn-
desirable
signals
may
be
expected
if
the set is
operatecl
under
or close
to steeì
bridges,
Llnder-
passes,
power
lines"
or
power
units.
Choose,
if
possible,
a
location
on
a hilltop
or
elevation.
Fiat
ground
is
desirable.
Normally,
reception
over water
is
better
than
over. land.
