The
transmitter cabinet should
be well grounded.
The cabinet
itself should be grounded by cable
to
meet underwriters'
regu-
lations.
The radio
frequency output, which
is
the
cabinet stud
on the top of the cabinet adjacent to the
feedthru bowl, should
go to
the
radio system ground.
At least
a 2"
copper strap
is
recommended.
In some
installations, this lead might be dressed
down inside the transmitter, behind
the side panel to the base,
and connecting
to
a
strap from there
to the
system ground.
Connecting
the
Load
The coaxial or open wire
transmission
line or the direct
coupled
antenna connects
to the
feedthru insulators
on the top of the
transmitter.
In the case of coaxial
transmission line or open
wire transmission
line, the
ground portion
of
the
transmission
line should be firmly secured
to
the top
of
the cabinet also,
so
that the ground path will not have
to
travel through the tríns-
mitter cabinet.
Where desired, the coaxial
transmission
line
may
be
brought up through
the
bottom
of
the cabinet
at
any number
of
the
convenient locations
as
will be quickly obvious
to
the install-
ing engineer's
eye.
