Capture AM like Never Before

The Twin Coil Ferrite® AM Antenna is ideal for improving most AM radio reception problems. No matter what kind of radio you're using, the antenna will significantly reduce nighttime fade out and help reduce static and distortion. The Twin Coil can double the audio clarity of any weak station during the day.

The antenna is designed to work with everything from portable radios without antenna connectors to home stereos with wire antenna terminals. The ferrite stick works on radios without antenna connectors.

The weather resistant antenna element is capable of picking up a clean signal some distance from your radio and sending it to the radio and overriding the static. This feature alone can make it the ideal AM antenna because there is no other way to get a clear signal.

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 will need to take the time to experiment to find the best location.

Patch cords, antenna, tuner, ferrite stick, mounting hardware and AC Adapter are included. Runs on included AC Adapter or 9V battery (not included).

  • Tuner Size: 3.25" W x 4.3" H x 1.4" D.
  • Weight: 4.5 oz.
  • Antenna Element Size: 8.6" W x 2.5" H x 1.5" D.

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.

Can I mount the Antenna Element outside?

It is possible to mount the Antenna Element outside in a sheltered area protected from weather. When using outdoors, you will need to apply silicone grease to the cable connector before plugging into the Antenna Element. Additionally, apply Coax-Seal to the perimeter seam of the plastic case, screw holes, cable connection and the ground lug. This will provide water resistance. If you are mounting the Antenna Element more than five feet from the Tuner Box, you will need to purchase our 50-foot Installation Kit.

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 were 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.

Does the Terk AM Advantage help with the Twin Coil Ferrite AM Antenna?

The Terk AM Advantage 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 Terk AM Advantage 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.

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.

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.
