These instructions cover the basic setup.
Attach one end of the 5" PS2 cable to the jack, labeled
To
Antenna, on the back of the TUNER CONTROL unit. The arrow
on
the plug should face up. Please, DO NOT force the plug into
the TUNER CONTROL. It will plug in nicely when the pins are
aligned.
TUNER CONTROL
The other end of the PS2 cable will plug into the jack on
the ANTENNA ELEMENT labeled To Control Box. The arrow on
this plug should also face up.

Getting Started
The first time you use the Justice Antenna it takes time,
planning, and a little bit of patience. You will need to re-
check and re-tune the unit to find the best position. After
you have found the best spot for the TUNER CONTROL, FERRITE
STICK, and ANTENNA ELEMENT, you can take the time to secure
and make permanent the installation to your liking. The
FERRITE STICK can be fixed to the radio using the included
hook and loop fastener. If you have a problem finding a
location for the ANTENNA ELEMENT that produces good results,
be sure to try different areas within 50'of your radio. If
you find a good position, you have the option of locating
the ANTENNA ELEMENT there. If you need to mount the ELEMENT
away from the radio for best reception, you may order
additional cable in 25'or 50' lengths. Please refer to the
inside cover of this manual for optional accessories.
Using the Justice Antenna
With a Portable Radio
To use the Justice with a radio that does not have antenna
connectors:
1. Find the patchcord with the 1/8" x RCA male connector.
2. Insert the FICA plug into the FERRITE STICK.
3. Insert the other end of the patchcord into the jack
labeled To Radio on the TUNER CONTROL. (See photo on page
5.)
Page 6
Using the Justice Antenna
With a Portable Radio
Place the TUNER CONTROL in a comfortable location relative
to your radio. Place the ANTENNA ELEMENT a few feet away.
If
the ANTENNA ELEMENT is placed too close to the radio, it
will cause noise on your radio.
Note: The iner knob is the fine tune control.
The outer knob is the coarse tune control.
1. Put the FERRITE STICK on top of the radio near the
center. The position shown in the photo (below right) is a
good position when the Justice Antenna is used with the CCRadio.
2. For testing purposes, tune your radio to any weak AM
station. It is important that the station be weak so you can
clearly detect the improvement in reception.
3. Rotate the FINE TUNE control, it will click on and the
red LED indicator light will come on. Turn the COARSE TUNE
control knob slowly and you will likely notice a change in
reception at some point on the dial. Adjust the control knob
until you notice the most improvement on your signal. Now
you can use the FINE TUNE control for further refinement.
4. Move the FERRITE STICK around the radio to find the
position that affects the signal the most. This position
will always be the same once you find the sweet spot.
5. Again, adjust the FINE TUNE on the TUNER CONTROL for the
best reception possible.
6. Now you can orientate the ANTENNA ELEMENT for best
reception. In most cases, the ELEMENT does not have to be
adjusted again. When radio noise is a problem, try rotating
the ELEMENT in the direction which reduces noise to a minimum.

Using the Justice Antenna
With a Home Stereo
You can directly connect the Justice Antenna to a home
stereo by connecting the 1/8" Mono x RCA control patchcord
to the RCA x two wire patchcord, as shown below left. You
can then attach one wire to the GROUND and one wire to the
AM terminals on the back of the receiver, as shown below
right. Most of the time you will find spring clips or screw
terminals. It will not matter which wire you connect to
which terminal.
Use the patchcord with the RCA plug on one end and 2 bare
wires on the other. Attach the bare wires to the AM and
GROUND antenna terminals on the back of your stereo system.
Plug the other end into the jack labeled To Radio on the
TUNER CONTROL. If you want to experiment or if your receiver
does not have antenna terminals, you can also use the
FERRITE STICK on whatever "loop"or "loopstick
antenna" that
was supplied with the receiver.
Note: The iner knob is the fine tune control.
The outer knob is the coarse tune control.
1. Tune your radio to any weak AM frequency. It is important
that the station be weak so you can clearly detect the
improvement in reception.
2. Rotate the FINE TUNE control, it will click on and the
red LED light indicator will come on. Turn the COARSE TUNE
control knob slowly and you will likely notice a change in
reception at some point on the dial. Turn the COARSE TUNE
control until you notice the most signal improvement.
3. Adjust the FINE TUNE control for the best reception
possible.
4. Now orientate the ANTENNA ELEMENT for best reception.
In
most cases, the ELEMENT does not have to be adjusted again.
After you have found the best spot for the TUNER CONTROL and
ANTENNA ELEMENT you can take the time to secure and make
permanent the installation to your liking.
Page 8
Using the Justice Antenna
With a Loop Antenna
Occasionally a home receiver will have a loop type antenna
on the back that is permanently attached. You can use the
FERRITE STICK in conjunction with a loop, as shown at right.
Move the FERRITE STICK around until you find the "sweet
spot" that works best.
Some older receivers have a ferrite stick similar to the
one
we provide. In this case, for best reception, put them
parallel to each other and find the "sweet spot".
In either
case, you can use the hook and loop fastener to keep the
FERRITE STICK in place.
Remote Installation of Antenna Element
If after thorough testing, you find the ANTENNA ELEMENT must
be mounted outdoors for best reception, you may order
additional cable in 25' or 50' lengths (refer to the inside
cover for optional accessories). Generally, you will only
need to mount the antenna outdoors if radio noise and static
reduce reception indoors.
When planning your remote installation try not to make
vertical runs with the long cables. If the cable is
vertical, it will pick up more radio noise than if you run
it horizontally because most radio noise is vertically
polarized. You can run a cable up to 75 feet by using a
special order cable coupler (refer to the inside cover for
optional accessories). At 100 feet you will experience about
a 25% loss in the performance. Always mount the ANTENNA
ELEMENT in a sheltered area to protect it from water. Two
mounting holes are provided on the back to help install the
unit. Refer to page 10 for important information regarding
Outdoor Installation Precautions.
Page 9
Remote Installation of Antenna Element (Cont.)
Included with the Optional Remote Installation Kit is
Silicone Grease and Coax-Seal. Apply silicone grease to the
cable connector before plugging into the ANTENNA ELEMENT.
Also apply Coax-Seal to the perimeter seam of the plastic
case, screw holes, cable connection and ground lug. This
will provide water resistance.
Outdoor Installation Precautions
Lightning Protection
Lightning poses a serious hazard to you and to your radio
equipment. Your antenna is a conductor. If it is struck by
lightning (or touched by a live power line), it will conduct
this electricity into your home.
Safety precautions require that you equip your antenna with
lightning protection equipment. The equipment needed and
installation methods can vary from area to area.
WE RECOMMEND THAT YOU HIRE A LICENSED, BONDED, AND
EXPERIENCED PROFESSIONAL TO HELP WITH OUTSIDE INSTALLATIONS.
An injury, of any kind, is simply not worth it. Please be
careful!
Radio Noise
If radio noise and static are a problem, start by finding
a
place as close as possible to the radio where the static is
absent. This is done by tuning a portable radio to a point
on the AM dial where there is no station and static is at
a
high level. Bring the portable near an outside wall or even
outside up to 50' away from your host radio. When you find
a
place without static, this is where you may want to mount
the Antenna Element. Please refer to Grounding the Antenna
Element on page 11, and Radio Noise Troubleshooting on page
12 for additional information.
Page 10
Grounding the Antenna Element
If radio noise is present, many times grounding the ANTENNA
ELEMENT will reduce it significantly. It is not necessary
to
ground the antenna if there is no radio noise. The easiest
way to ground the ANTENNA ELEMENT is to place a #10 solid
copper wire three or four feet into Ground Lug the ground.
The end of the wire is then connected to the ground lug on
the ANTENNA ELEMENT. The wire can either be wrapped around
the lug or shaped with needle nose pliers first. You can
mount the ELEMENT away from where you have placed the three
or four feet of wire into the ground but it is best to keep
the distance as short as possible. If there is radio noise,
the lead from the grounding point to the ANTENNA ELEMENT may
pick up additional radio noise. Moisture content of the soil
may also affect performance. Damp soil is better than dry
soil.
Frequently Asked Questions
Q. Does the Select-A-Tenna help with the Justice Antenna?
A. The Select-A-Tenna when used in conjunction with the
Justice Antenna, produces curious results and in some cases
marked improvement.
Special note to people who love AM radio: I use my Select-
A-Tenna along with my Justice Twin Coil Ferrite (TCF) for
best reception. Heavy static normally destroys radio
reception on my bedside CCRadio. I now use the Select-A-
Tenna to eliminate noise at the radio by careful tuning. I
then import a clean signal from the Justice antenna head
only 15 feet away. I have never received a better signal in
my life. - Bob Crane
Q. Where can I get more information on the Justice Antenna
Specifications?
A. Please check www.ccrane.com for complete technical specifications.

Radio Noise Troubleshooting
AM RADIO NOISE PROBLEMS AND POSSIBLE SOLUTIONS
Annoying buzzes are many times transmitted through an AM
radio. Here is a check-off list of the most likely causes:
* Dimmer switch.
* Fluorescent light.
* "Touch lamp" type light fixture (even when turned
off)
* Automatic on and off night lights
* Outdoor yard lights which come on automatically.
* Electronic bug and pest controllers.
* A light bulb that is about to burn out.
* A faulty electrical switch of any kind.
* A nearby television set.
* A store that has a fluorescent light or a public
recreation room that has fluorescent lights located near you.
* Blinking bulbs of all kinds such as Christmas tree lights.
* If you live in an apartment a neighbor's dimmer switch
could be the culprit.
* Scanners of all types.
* Dirty insulators on a nearby power pole allowing arcing.
* Electric blanket.
* Smoke detectors that run from AC current (battery operated
is OK).
It is best to eliminate the interference at its source.
Here's a list of possible solutions:
* The most obvious is to turn off the offending device.
* Try a battery operated radio to see if the interference
is
coming in from the AC 120v line, through the air, or both.
* Turn off the circuit breakers to see if the noise stops.
If it does, then you know it is something in your house.
Turn off one circuit at a time to isolate where the noise
is
coming from.
* Use a battery operated radio as a direction finder. Turn
the radio until the loudest noise is heard and the front and
back of the radio will point to the noise origin.
* Carry a radio around the neighbor-hood and see if you can
find the origin of the noise. Ask other neighbors if they
have the same problem.
* If a power pole is suspected, call check the area and
possibly wash the insulators. Dirty power pole insulators
are sometimes a cause of difficult-to-find radio
interference.
* If you have a hum in your receiver from AC line noise
sometimes grounding the radio can reduce the hum greatly.
Finding a good earth ground may be difficult.
