If you're one of the millions who tune into AM radio for daily news, sports, politics, religion, or talk show broadcasts, you should know about the AM Advantage. The passive (non-powered) AM Advantage from Terk dramatically improves the AM reception on any stereo receiver, tuner, portable, or table radio. It easily outperforms the AM Loop antennas included with most receivers.

Terk's Pin-Dot™ Pre-Tuning system lets you tune out noise and interference with a twist of the tuning dial on the top of the base. By tuning the antenna to the same frequency as the receiver, you can fine-tune reception for each station and experience greater clarity than ever before.

The AM Advantage is a total AM solution; it works best when connected to your receiver's AM antenna input, but wireless operation is also possible simply by placing the AM Advantage near the radio and tuning it until reception is clearer. This method should be used with clock radios, boomboxes, and other units which lack an antenna input.


  • tuning dial to adjust reception for each station
  • wireless operation for use with radios lacking an AM input
  • 9-1/2"W x 9-1/2"H x 2-3/8"D

Works perfectly

I bought this to overcome the interference put out by my plasma tv in order to better enjoy my multi-room listening options. It went from unlistenable to clear as a bell. It really is too bad that they are discontinued.

Crutchfield Customer Review (What's this?)

In the past year I started experiencing interference with the reception of my favorite AM radio station. At times reception was impossible. I tried a new, expensive radio and two different AM antennas but still had the problem. This antenna has solved the interference problem; I can listen the this station clearly. I have to occasionally adjust the orientation of the loop but can consistently listen to this station without the interference. Purchasing this antenna was money well spent.



Great Antenna

I used this antenna to recieve my favorate
baceball brodcast of The Atlanta Braves.
Not exactly clear but is hearable {due to weather
conditions} . I highly recremend it.



Reception Much Improved

Crutchfield Customer Review (What's this?)

I bought this thing so I could listen to the baseball broadcast without that nasty static and interference from neighboring stations I was getting with my old loop antenna. It was driving me nuts. I get poor signal coverage in my area on all bands (AM/FM/UHF/VHF), so I wasn't expecting a miracle, but this thing does an admirable job. The pin-dot tuning really did the trick. My reception still gets a little noisy after sundown, but it's worlds apart from where it was. I'm very happy with this antenna.



Really Works!

As a long time DX'er (a Radio Hobbyist who tunes long distance Radio Signals)I have used the Terk MW AM antennas for several years with very good results. This model of Terk Antennas is a "Magnetic Loop" antenna (meaning that its'design responds to the "Magnetic Component" of an RF signal. The "Magnetic Component", as apposed to the "Electronic Component" is the quietest part of RF signals and at the AM Broadcast Band portion of the RF spectrum is where the "Magnetic Component" is most responsive. As we tune higher up in the Radio Spectrum this Magnetic Component becomes less responsive to "Loop Antennas".
The "Magnetic Loop Antenna" works best when used as an "Inductive Coupler", meaning there is no need to hook up to a radio using wires (most consumer class radios do not provide antenna hook up ports). The RF signal is transfered from the Loop to the radio's internal antenna magneticially and the use of a "tunning capacitor" on the base of the Terk Antenna allows the listener to "Peak" the signal very close to the frequency being received. This "Coupling and Peaking" allows the user to both greatly improve otherwise weak signals and to avoid interference and noise (you can rotate the Loop in such a manner that it accentuates the signal and "null out" the source of the noise.
Simply put, the Magnetic Loop antenna, which this Terk Model is, can greatly improve any Medium Wave BCB signal and, there is no need to use wires!(you can both add a wire to the Terk or use a wire to connect the antenna if needed). I would not be without one when I listen.



Antenna Improved Weak Reception

Written by: Owen from Glenmoore, PA on July 14, 2005

Crutchfield Customer Review (What's this?)

I recently bought this antenna in order to deal with the poor reception I had on my favorite talk radio station. Essentially, I did a controlled experiment using my old loop antenna using the signals from several stations which used to be weak and static-filled. All stations are now quite clear once the antenna is oriented and tuned properly. While it is not convenient having to tune the antenna to the optimal signal, it is far better than poor reception.

Another bonus is that it is much more attractive than my old loop antenna.

Product Research


Passive Antenna: The antenna is a passive, AM only antenna, which is shaped like an open hoop. 

Improved Performance: Typically, this antenna provides better results than the AM loop antennas included with most tuners and receivers. It won't work as well as a properly installed and grounded exterior AM antenna, but it is a good alternative when you do not want to, or can't, install an external AM antenna.

Adjustable Tuning: There's a tuning dial on the top of the base which allows you to tune the antenna from 535KHz to 1700KHz (the AM frequency range).  By tuning the antenna to the same frequency as the receiver you can adjust reception for each station.

Output: There is a mono mini-jack output on the rear of the base which is used with the supplied cord to connect the antenna to the receiver.  The cord terminates in two bare wires (one of which is the ground), which need to be inserted into your tuner's AM antenna input. Either of the two ends can be used as a ground.

Wireless operation: Although the antenna works best when connected to an AM antenna input, it will also function simply by placing the unit near the radio and tuning the antenna until reception is clearer. This allows the antenna to be used with clock radios, boom boxes and other units which do not have antenna inputs. The antenna should be tried on all four sides of the unit to see where it will work best.
