Initial Setup
Connection to Radio and
Antenna
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.
Connecting Antenna Element
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.
Antenna Element
The rst 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 nd 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 xed to
the radio using the included hook and loop fastener.
If you have a problem nding a location for the Antenna Element that
produces good results, be sure to try di󰀨erent areas within 50' of your
radio. If you nd a good position, you have the option of locating the
Antenna Element there. If you need to mount the Antenna Element away
from the radio for best reception, you may order additional cable in
longer lengths.

Antenna Operation
With a Portable Radio (Continued)
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. Place the Ferrite Stick on top
of the radio near the center.
Placement will vary depending on
where the internal AM antenna
of the radio is located.
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 renement.
4. Move the Ferrite Stick around the radio
to nd the position that a󰀨ects 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 best reception
possible.
6. Now you can orientate the Antenna Element for best reception. In
most cases, the Antenna Element does not have to be adjusted again.
When radio noise is a problem, try rotating the Antenna Element in the
direction which reduces noise to a minimum.

Antenna Operation
With a Home Stereo
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
control patchcord to the RCA x two
wire patchcord, as shown.
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. Most of the time
you will nd 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 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 Antenna 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.

With a Loop Antenna
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 nd the “sweet spot” that works best.
't

Antenna Operation
With a Loop Antenna (Continued)
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 nd 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 nd the
Antenna Element must be mounted
outdoors for best reception, you may
order additional cable in longer lengths
(refer to ccrane.com 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 ccrane.com 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 14 for important information regarding Outdoor
Installation Precautions.
If using outdoors, 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.

TWIN COIL FERRITE AM ANTENNAPage 14
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 nding 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 nd a place
without static, this is where you may want to mount the Antenna Element.
Please refer to Grounding the Antenna Element above, and Radio Noise
Troubleshooting on page 15 for additional information.
Grounding the Antenna Element
If radio noise is present, many times
grounding the Antenna Element will
reduce it signicantly. It is not
necessary to ground the antenna if
there is no radio noise.
The easiest way to ground the
Antenna Element is to use a #10 solid
copper wire attached to a grounding rod
inserted into the ground three to four feet deep. 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 rst.
You can mount the Antenna Element away from where you have placed
the grounding wire attached to the grounding rod 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 a󰀨ect performance. Damp soil is
better than dry soil.

Radio Noise Troubleshooting
AM radio noise problems and possible solutions.
If you hear an annoying buzz when listening to AM radio, it’s most
likely radio noise. Here are some of the usual culprits:
• Dimmer switch (even in an adjacent room).
• Lights: uorescent light, “touch lamp” type xtures, automatic night
lights, motion-activated outdoor lights, dying bulbs, blinking bulbs.
• Nearby television or computer.
• Electronic bug and pest controllers.
• Faulty electrical switch.
• Radios & scanners.
• Dirty insulators on a nearby power pole.
• Electric blanket.
• Smoke detectors that run from an AC current (battery operated
units are OK).
• C-Pap machines.
Now what can you do about it?
• Turn o󰀨 the circuit breakers to see if the noise stops, and if the source
comes from inside your house. Turn o󰀨 one circuit at a time to isolate
the source of the noise.
• Using a battery-operated radio, check if the interference comes from
the AC 120V line, through the air, or both. To locate the direction of
the noise, turn the radio until you hear the loudest noise. The front
and the back of the radio will point to the noise origin.
• If the noise comes from outside, carry the radio around the neighbor
hood to check for the origin of the noise. Ask your neighbors if they
hear the same noise.
• If you suspect a power pole, call the utility company. Dirty power pole
insulators are sometimes a cause of hard-to-nd radio interference.
• Sometimes grounding can greatly reduce the hum from AC line noise.
Unfortunately, most radios do not have a ground connection. Finding
a good earth ground may also be di󰀩cult.
