INSTALLATION
LOCATION
When vou install the new ~lua. make sure
it
is
connected
The amplifier should not
be
operated in excessively warm
locations or near heating vents or radiators. Free air
circulation around and through the amplifier cabinet, and an
unobstructed air inlet for the blower should
be
provided. No
lbooks, magazines, or equipment should be placed on top of
the cabinet to impede the free flow of air.
according to your local electrical code. Keep in mind that
the green line cord wire
is
connected to the amplifier chassis.
For your convenience in identifying conductors, one edge of
the heavy line cord
is
beaded. The other edge
is
smooth.
POWER CONSIDERATIONS
ANTENNA
Because of the power involved, this Amplifier should
preferably be served by
its
own 240 VAC electric service
line, having three 12 gauge conductors and fused in each
'hot" wire for 10 amperes. However, if a single 240 VAC
line must serve the entire station, make an effort to connect
your equipment
so
the load will be balanced between the
two 'hot" wires as nearly as possible.
If only 120 VAC can be provided, use a separate line having
10 gauge conductors and 20 ampere fuses.
DO NOT use this Amplifier at
its
full ratings on a regular
house wiring circuit, as the ratings of the wire will almost
certainly
be
exceeded.
Avoid excessively long runs of wire from your service
entrance. A heavy flow of current in such a line results in a
voltage drop which can affect the performance of your
equipment.
If you use a power cord plug that
is
different from the one
now on the power cord, cut off the furnished plug.
The output circuit of the Amplifier
is
designed for
connection to an unbalanced transmission line of 50
Cl
characteristic impedance. Lines of other characteristic
impedance may be used providing the SWR (standing wave
ratio) does not exceed 2:l.
The antenna connector is a UHF type SO-239. A mating
PL-259 plug
is
furnished for your transmission line.
See
"Equipment Interconnections" for information on how to
install this plug.
Coaxial cables RG-8/U, RG-1 l/U, or similar types, should
be
used for the transmission line. The smaller types RG-58/U
and RG-59/U are not recommended because of the power
level.
The "A.R.R.L. Antenna Book" is commonly available and
includes comprehensive reference work on transmiision lines
and antennas. Other similar handbooks for the amateur are
offered for sale and can often
be
found in a public library.
