The Twin Coil Ferrite® AM Antenna is ideal for boosting AM radio reception and solving most AM reception problems. No matter what kind of radio you're using, the antenna will reduce 90% of nighttime fade out, and help reduce static and distortion. The antenna can also double the signal strength of any weak station during the day.

The antenna was designed to work with everything from portable radios to home stereos with wire antenna terminals. The Twin Coil's wireless ferrite stick works on radios without antenna connections. The antenna element is capable of pulling in a clean signal some distance from your radio. It then sends the signal to your radio to override static. This feature alone can make it the ideal AM antenna because there is no other way to get a clean signal. The Twin Coil has the highest gain of any commercial AM antenna.

The antenna element has directional characteristics. By rotating the antenna element in a window or outside you can improve the signal strength. As with any AM Antenna, you may need to take the time to experiment to find the best location.

With the included 25 foot remote installation kit, you can set the antenna element closer to a window or even outside (away from possible noise and interference), and dramatically improve reception on weak AM stations in brick, stucco, or metal-sided homes. You'd use the coupler (also included) if you plan on connecting the 25 foot cable to the 50 foot cable, or if you need to connect either of the extension cables to the five-foot cable that's also included with the antenna.

Well designed, versatile MW antenna
Allows even an inexpensive AM radio to pull in extremely weak signals.
Highly directional ferrite antenna nulls unwanted signals
Optional longer cables allows ferrite antenna to be placed in quieter location.
Best Uses
Excellent for MW DXing. This device rivels my 6' passive loop. Remote ferrite antenna can be tuned at listening position.
If you enjoy listening to distant AM radio stations, BUY ONE, you won't regret it. I have the remote ferrite antenna on a rotatable wooden turntable, which allows me to peak desired stations, and null unwanted signals/noise.

Listening to late night radio
listening to day time radio
Wonderful piece of kit hear, I can listen to WSM as if it's a local station, I have the standard Twin Coil Ferrite, I am posting hear as I cant find that one but I can tell you this, you'll love the antenna. It has low distortion and low noise, now sense its active it'll raze the noiseflore a little bit but thats how active things work, it's a little amplifier in there.

Best AM signal I've ever heard!!
I ordered an antenna system from your company a few weeks ago. I installed it as the directions stated. I mounted it on the top of my shop building. My shop is all metal roof and sides. I had no AM reception before this. I now can dial in the best AM signal I have ever heard. Truly amazing product for my purpose. I fashioned a, approximately, 16 piece of 4 PVC pipe that is cut on a 45° angle on both ends to slide the outdoor portion of the system in. It should stay plenty dry. Thanks C Crane

Twin Coil AM Ferrite Antenna
The difference with my 1938 Zenith floor model with an 80 ft. wire 10 ft. off the ground
and this twin coil from C.Crane was as night and day. The suppression of static and volume increase was so great I've ordered a second one for my other collectable radio.
None I'm aware of.
Best Uses
Works very well with tube radios where static is a problem.
Not cheap, but miles ahead of lower cost antennas of a similar type.

  • Will the Twin Coil Ferrite AM Antenna improve the AM reception on my radio?

    Yes. The Twin Coil Ferrite AM Antenna will improve the AM reception on any radio. It increases daytime and nighttime signal strength. The Twin Coil Ferrite AM Antenna decreases fadeout, distortion, and can reduce static. With the ferrite patch cord, RCA patch cord, hardwire patch cord, or optional 1/8" x RCA patch cord, you can connect the Twin Coil Ferrite AM Antenna to virtually any type of radio.

  • How much cable comes with the Twin Coil Ferrite AM Antenna?

    Five feet. Additional lengths of 25 feet and 50 feet are available.

  • What is the maximum amount of cable that you can use with the Twin Coil Ferrite AM Antenna?

    You can use up to 75 feet of extra cable before you get line loss.

  • What kind of cable does the Twin Coil Ferrite AM Antenna come with?

    The Twin Coil Ferrite AM Antenna comes with five feet of "six pin mini din six conductor shielded cable." The cable connects to the Twin Coil Ferrite AM Antenna using PS2 connectors, which are connectors commonly found on computer keyboards and computer mice.

  • Is there an attachment to connect two Twin Coil Ferrite AM antenna cables together?

    Yes. C Crane has a Cable Coupler adapter available that will connect two Antenna cables together.

  • How do I connect my radio to the Twin Coil Ferrite AM Antenna if I don't have an external AM antenna connection?

    The Twin Coil Ferrite AM Antenna comes with a ferrite patch cord. This lets you connect it to a radio that doesn't have an external AM antenna connection. The ferrite rod is placed near the internal ferrite antenna on your radio.

  • Can the Twin Coil Ferrite AM Antenna be used in a car?

    Yes. It probably won't help in a moving car, but it works great in a mobile home or stationary RV. If your mobile home or stationary RV has aluminum siding, we recommend an extension cable to get the antenna head outside where the radio signals are.

  • Can the Twin Coil Ferrite AM Antenna be grounded to an electrical outlet house ground or should I use a copper pipe?

    In most cases grounding of the antenna head is not required. A ground would only be used if you had excessive noise when the antenna is operating outside. If you feel the need to try grounding the antenna head, then run the ground wire from the antenna head to a good earth ground. A good earth ground is either a ground rod typically a 5/8 X 8 copper clad steel or a copper pipe cold water line running into the earth. Copper ground wire can usually be purchased at your local hardware store. An ideal ground has the metal in contact with moist soil.

    Note: Grounding the antenna to the center screw on an electrical outlet will likely cause a hum on your radio.

  • How much dB gain does the Twin Coil Ferrite AM Antenna have?

    The Twin Coil Ferrite AM Antenna has about 32 dB gain.

  • Does the Select-A-Tenna help with the Twin Coil Ferrite AM Antenna?

    The Select-A-Tenna when used in conjunction with the Twin Coil Ferrite AM Antenna, produces curious results and in some cases marked improvement. However, if your radio is in a brick, stucco, aluminum sided, or other non conducive building material, the Select-A-Tenna will have insignificant results.

  • How long will a 9 V battery last?

    A fresh 9-Volt battery will last approximately 40 hours.

  • How do I connect the Twin Coil Ferrite AM Antenna to radios that have external antenna connections?

    The cable connection from the tuning box to the radio has a 1/8" male mono plug on one end (tuner box end) and an RCA male on the other. We include a short red patch cord that has an RCA female on one end and that it splits in to two separate red wires. These wires connect to the AM antenna screw and ground screw. One of the red wires has a black stripe on it. This wire connects to the ground screw and the plain red wire connects to the AM antenna screw.

  • Where does the Twin Coil Ferrite AM Antenna hook up to the Bose radio?

    The Twin Coil Ferrite AM Antenna has a small ferrite stick that should be placed under the center of the left wing of the Bose (as it faces you) Placing the ferrite stick in this position will make an inductive connection with the internal ferrite stick of the Bose.

  • Is there Line loss on the Twin Coil Ferrite AM Antenna's extension kits?

    Yes there is loss however the signal to noise ratio is good up to 75' (75' is the maximum distance we recommend).

  • Why do the extension kits for the Twin Coil Ferrite AM Antenna not work on my radio?

    To work properly, the 25 and 50-foot extension cables must not be coiled up. The coiled cable effectively cancels out the electromagnetic energy. Uncoil the cable for proper reception.

  • Can I use RG6 or RG59 cabling with the Twin Coil Ferrite AM Antenna?

    No, do not use RG6 or RG59 cables with your Twin Coil Ferrite AM Antenna. The Twin Coil Ferrite AM Antenna requires a six-pin Mini DN cable. The cable must have good shielding and other properties to work well with theTwin Coil Ferrite AM Antenna. The Mini DN has six wires in it that are required to supply voltage, signal and antenna tuning between the antenna element and the tuning unit.

  • No change in signal strength with Twin Coil Ferrite Antenna

    The Twin Coil Ferrite Antenna is extremely directional. It must be rotated when tuning in AM stations. If the remote Ferrite Stick Antenna is not rotated, no increase in signal strength may be noticed. Check the connections between the antenna element and tuning box and between the radio and the radio and tuning box.
