RF Connections
Prior
to
operation
of
the
transmitter,
the
RF
output
must
be
connected
to
a
known
good
test
load
or
antenna.
Connect
the
load/antenna
using
the
correct
size
connector
and
transmission
line
for
your
model
of
transmitter.
It
is
a
good
practice
to
use
the
minimum
number
of
elbows
to
get
the
best
performance
from
your
transmitting
system.
If
there
is
a
patch
panel
or
an
RF
Switch
for
a
load/antenna,
an
interlock
connection
is
required
to
J1
of
the
FAX.
See
Table

for
correct
pins.
These
can
be
installed
in
the
dummy
connector
supplied
by
Harris
Broadcast.
Note
Initial testing into a 50 ohm test load is recommended. The VSWR of the load should be no greater than
1.05:1. The VSWR of the antenna should be no greater than 1.1:1.
