Thank you for purchasing the Twin Coil Ferrite AM Antenna by
C.Crane. The antenna can be used on a small portable or desktop
radio with excellent results. It is also the first AM antenna that can
provide exceptional improvement to a large home stereo system. It
can actually reduce static and radio noise on AM.

Remove the battery compartment cover on
the bottom of the TUNER CONTROL.
Connect the battery. The antenna will run
for approximately 45 hours on battery
power. The 9-volt battery is automatically
disconnected when the AC adapter is
plugged in.
The AC adapter is simply plugged
into the wall, and then into jack
labeled "9V DC" on the back of the
TUNER CONTROL.

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 NOTforce the plug into the TUNER
CONTROL. It will plug in nicely when the pins are aligned.

Initial Setup
ANTENNA ELEMENT
The first time you use the Twin Coil Ferrite AM Antenna by C.Crane
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.
To use the Twin Coil Ferrite AM Antenna with a radio that does not
have antenna connectors:
1. Find the patchcord with the
1/8" x RCA male connector.
2. Insert the RCA 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.)

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.
1. Put the FERRITE STICK on top of the radio near the center. The
position shown in the photo (below) is a good position when the
Twin Coil Ferrite AM Antenna by
C.Crane 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 yoursignal. Now you can use the FINE
TUNE control for further refinement.
4. Move the FERRITE STICK around the radio to find theposition
that affects the signal the most. This position is the “sweet spot”,
or the best position.
5. Again, adjust the FINE TUNE on the TUNER CONTROL for the
bestreception 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.

With a Portable Radio
You can directly connect the Twin Coil Ferrite AM Antenna by
C.Crane to a home stereo by connecting the 1/8" Mono x RCA con-
trol 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 terminal 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.
Next, 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.
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
pointon 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.

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' by using a special order cable coupler (refer to the
inside cover for optional accessories). At 100' 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.
Occasionally a home receiver will
include a loop type antenna. 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.

With a Loop Antenna
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 THATYOU 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!
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.
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.
