Ground Connection; Ignition Noise - Kenwood TS-50S Instruction Manual

1 INSTALLATION AND CONNECTION
GROUND CONNECTION
The ground, which is the other half of the antenna
system, is very important when using a mobile whip
antenna. Connect the feed line ground for the antenna
securely to the vehicle's chassis, and be certain to
bond (electrically connect) the vehicle body to the
chassis. The sheet metal will provide the primary
ground plane, so be sure to establish a good RF
connection from the feed line to both the chassis and
the body. For comprehensive information on mobile
antennas and their successful installation and
optimization, refer to the ARRL Handbook or similar
publications.
If your car has plastiC bumpers, make sure to ground
the antenna mount to the body and the chassis of the
car.
IGNITION NOISE
This transceiver has been designed with a Noise
Blanker to filter ignition noise. However, some cars
may generate excessive ignition noise. If there is
excessive noise, use suppressor spark plugs (with
resistors), or perform other countermeasures as may
be required to reduce these undesired electrically
generated noises. The ARRL Handbook, or other
similar reference, has a wealth of information regarding
this topic.
Note:
The negative lead from the battery must remain disconnected
until all connections are completed,
In
order to prevent the
possibility of an accidental short circuit during installation.
2 After installation and wiring, confirm that all work has been
performed correctly, then reconnect the negative battery lead.
3
If the fuse blows, check that the power cable has not been
damaged or short circuited, is not pinched Of squashed, etc.
After resolving the problem, replace the
fuse
with one of the
same type and rating.
4 After the wiring is finished, wrap the fuse holder with heat·
resistant tape
to
protect the fuse against heat and moisture.
5
DO NOT
remove the fuse holder even if the power cable is
too
long.
