The Twin Coil Ferrite® AM Antenna is ideal for boosting most AM radio 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 that don't have antenna connectors.

The antenna element is capable of pulling in a clean signal some distance from your radio. It then send the signal to your radio and overriding the static. This feature alone can make it the ideal AM antenna because there is no other way to get a clean signal. It 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.

Great antenna
Small size
Excellent performance
interesting results
great value
wires can be annoying
difficult learning curve
Best Uses
Great for DX playing
clear up fuzzy stations
pull in weak/nonexistant stations
This is a great little antenna though it took me a good week or two to figure out how best to use it. Since then, I've been amazed at what it can do for my radios. Even the radios I have which are great at DX'ing, this antenna improves them. It's a shame that it looks to be discontinued.

Great antenna system
Pulls in and amplifies weak stations
Tuning stations in makes one feel part of the antenna system. Fits my needs perfectly. Quality build and materials.
Set up is easy and manual well written. I was concerned about picking up noise and that placing the antenna element would be difficult. This was not the case. This system worked very well for me.

A) able to significantly boost a weak AM signal.
B) able to tune out annoying 60-Hz buzz from power lines and plugged-in devices.
It means additional gear to deal with when running your radio. Not really a problem.
Best Uses
Tuning into distant or weak stations that are otherwise problematic to receive.
Tuning out noise that an internal antenna simply cannot since it has to be in the same location as your radio.
Requires closely following the instructions and some patience to set up. Specifically, if you don't have direct connections for an external antenna, take the time to really find the sweet spot for the ferrite bar. Both the location AND the angle are important. It can make a huge difference. Additionally, finding the ideal location for the antenna itself is also worth spending time on. Example: Apparently I only have ONE spot and ONE angle in my room that completely tunes out the 60-Hz buzz from power lines and devices. It took me a while to find it. If you DO have a direct connection for the antenna leads, if your radio has an internal/external antenna switch, be sure it is switched to external. Also, probably because of the time (years) my internal/external antenna switch was set to internal, I had to exercise the switch about 20 times before I got a good connection with the external antenna. But now that I do, I love it!

I use this for the occasional AM radio from my main receiver which has a WiFi device on top (A Logitech SqueezeBox) which creates huge interference. This antenna, with the coil moved a few feet from the WiFi device, cuts through most of the interference and allows me to keep the Squeezebox plugged in all the time while still using the main stereo for AM radio now and then.

This antenna did improve the reception on two CCRadio-2s BUT it actually DECREASED the AM reception slightly on a CCRadio-SW.

This antenna works good. I used it on an old Sangean ats803 and it seems to be designed for it since it plugged right into it's antenna jack and not only made the reception better, it brought to life the 1630-1700 part which the radio's own ferrite bar has no control over-nice! I currently use it for an old Pioneer receiver and it helps a lot. The only down side and it's really no fault of the antenna is that it will amplify any RF noise but tweaking the fine tune knob helps reduce a lot of it. The advertising on the box states that it dramatically reduces night time fade out. That has not been my experience. I'm no expert but I think that fade out has more to do with the signal and not the radio.

I felt this didn't do as well as I thought it would. Maybe were are in too many woods.

This really makes a difference in my radio reception. I live in a small town "in the middle of nowhere," a fringe area for radio reception, but the Twin Coil Ferrite Antenna enables me to pick up loud and clear even the weak local AM station located in a town 30 miles away. I can't pick it up so that it's listenable without this antenna. I use the legendary Sony ICF 2010 radio, and this antenna makes a big improvement over the radio's inherent capabilities.

Had excellent results. Placed antenna next to window of high rise building and then with the extra cost 25 foot extension, placed radio on desk. Reception is noticeable better than when radio itself was placed next to window.

This is a remarkable effective antenna. I have a very expensive audio system that I use for music and occasionally TV and movies, but I also listen to AM talk radio. I always had static and terrible reception before I bought this; the audio store was very skeptical of this product, but I bought it anyway and installed it myself. The quality of the sound was so amazing that I was shocked, and so were the audio "experts". This antenna makes more difference in AM sound quality than the ridiculous amount of money I spent for all the components. Buy it if you want better AM reception. I have had it for at least a year and there are no problems of any kind. 5 stars easily.

This product is used with a Grundig S450DLX. It affords equal, but not better, reception when the radio is NOT near a window. Possibly the TWIN-coil ferrite can improve reception in some cases, but so far has not in my experiences.

  • 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.
