AN-100 Tunable Passive AM Radio Loop Antenna for All Brands Like Kaito,Sony,Panasonic,Grundig and More

Bought this off Amazon and fullfilled by Electronix. Not the first time I've dealt with this combination and results were excellant as always. I bought this to replace a Select A Tenna that I lent to a coworker who was getting into m.w. dx'ing to show him how good these small tuned loops are. Unfortunately I. Don't expect to get this back anytime soon and the Select A Tenna is no longer in production. After reading good reviews ofthe AN 100 I bought one and am very impressed with it. Normally I wait at least a month to review a product after I purchase it to avoid new "toy" enthusiasm, but being aquainted with the Select A Tenna and it's performance I felt a review was in order and also to point out a few quality concerns regarding this antenna. First though I'll tell you that it's every bit as capable as the Select A Tenna, maybe better. It seems to tune better across the band. As I neared the end of the mw band on the Select A Tenna it's tuning capabilities seemed to be be rather ineffective. Not so with the AN 100. From 550khz to 1710khz the tuning knob is effective in bringing in the desired signal. Probably the most impressive thing about it is it's ability to FINALLY make my Tecsun PL 880 to perform as a very good A.M. or M.W. radio. I was always dissapointed in this otherwise excellant radios M.W. performance. The noise floor was excessive in my opinion and the AN100 rectifies this. It now is all most on a par with what I consider the benchmark of portable radios the Sony 7600gr. And it also improves this excellent radios reception as well although to a lesser extent. Directly coupled to my Grundig Satellit 750 it allows this excellent radio to be all that it can be. I can finally use the wide band without excessive overloading highly recommend this antenna particularly at it's current price point. As to the quality issues, I have read of several cases where this antenna was received with a loose tuning knob and or loose connecting cable input jack. Mine was received with both of these loose but they can be tightened with little effort. Tightening the input jack requires a small standard screwdriver to turn it's retaining ring clockwise to tighten. To tighten the tuning knob, pull the knob off to reveal the adaptor which is retained by a small phillips screw. Two other phillips screws are also visable at this point. The center adapter screw is the one to tighten but since the other two are exposed at this point you may want to snug them up as well. Overall, this is a great antenna, a near must have for the serious dx'r and the casual user will appreciate it's ability to improve the reception of their favorite station.

I am certain that the people that returned this item simply didn't use it properly or were impatient. If you have a radio such as a G.E. Superradio, some of the Grundigs or other high end radios that have excellent ferrite antennas already in them, this antenna will show little improvement on strong signals. If you have a radio with a tiny ferrite antenna or no antenna at all, this loop will work wonders! I have tested this loop with all of my radios and I have a lot. This unit excels at pulling in and cleaning up stations in the daytime even if it is a strong station for you, if you tune slowly and find the sweet spot if will null out adjacent stations and hiss etc. If you have a radio with one of those cheap loops that connect to terminals in the back of the radio, place that crappy loop inside of this Kaito loop and slowly tune. You will be amazed at what it will do for you. I am also having a blast DXing at night with this loop. I use either my Sangean ATS-909 or my Meloson DSP multiband radio. What a wonderful, simple addition to listening to the radio. Greatly adds to my pleasure for DX radio. You have to first find the spot on your radio where the ferrite antenna is by moving the loop slowly along the back or front of the radio. This works by induction. The loop doesn't actually have to touch your radio, just get it close. When you are in the right spot you will know it by the sound quality of the station. It will either make it stronger or make it weaker. Then you slowly use the tuning knob on the loop to find the sweet spot. On my radios, 850 correlates to the exact middle of the tuning knob on the loop. At night, I am able to null out adjacent stations, it REALLY helps. This is a great product. Folks just need to be a little patient and use a light touch with the tuning knob on the loop. Thanks Kaito!

I received the Tecsun branded version of this loop antenna and it works comparably to the Terk Advantage which I also have. I wanted another loop and the Kaito (Tecsun) is less expensive so I gave it a try. While the Terk feels sturdier, I like the Tecsun for its looks and the more convenient placement of the tuning knob. These loops are fun to use and magically seem to increase reception when tuned in. To use these you need to tune the antenna separately after you first tune your radio to the desired station. This may be a bother for some people but it is the price you pay for improved reception. I find no obvious difference whether using the antenna inductively or wired so I don't bother with the wires. (The radio needs to have an internal antenna for inductive coupling - most do - but some stereo receivers don't. See my review of the Terk Advantage for more details.) So if you have only fair AM reception now and want to increase it, this loop should work very well for a reasonable price. It's a nice product. If you are getting poor reception now due to building construction issues or noise problems, then this antenna might not help. The Physics here is simple and has to increase the signal delivered to your radio. But if you don't have much of a good signal to work with, you'll likely be disappointed. Addendum: After only three months of use, the operation of the tuning control produced static sounds when reaching the proper adjustment point. This tuning point seemed to drop away when I removed my hand from the control, thus requiring multiple retunings. I suspect that the dial controls a cheap potentiometer which requires spraying with a contact cleaner. Unfortunately, I can't figure how to take the antenna apart without breaking it so I will just have to live with it. I have removed one star.

Arrived Quickly. Worked as suggested. Will buy another.

This tunable AM antenna can improve AM reception significantly, but the tuning is 'mushy'. When you turn the knob, the reception doesn't suddenly get better when you hit the proper tuning frequency as it should, it's a gradual improvement - you have to turn it back and forth to try to find the best spot. In comparison, on my old Select-A-Tenna, the reception will suddenly and sharply improve when you hit the right tuning frequency - a sharp "bing!". Though this Kaito is 1/3 the cost, and the Select-A-Tenna seems to not be made any more. In terms of looks and ergonomics, this Kaito AN-100 is nice...you can't ask for much more at this low price.

I had my doubts about this antenna before I purchased it. Turns out to be one of the best purchases I've made! At a garage sale, I purchased a Yamaha AV receiver model RX-V371 for my garage man cave. I live in the city, (St.Paul/Minneapolis) and sadly I could not get my favorite AM station, WCCO 830, to listen to the Minnesota Twins baseball games. The signal in my area is strong, but in my garage, there was so much noise and static you could barely hear the station. I had one of those standard cheap loop antennas connected, but that didn't do anything to help. I connected the 2 wires from the Kaito antenna to the back of the Yamaha receiver, one wire to the external AM antenna port, the other wire to the ground port. I had to move the antenna into position where I could hear improved signal/sound. This is important to find the right position, in my case it was about 2 feet from the receiver. The signal was ok, but still not very good at all. Then, I adjusted the tuning dial on the antenna, and amazingly enough it cleared up all the static and noise, and I now have almost perfect reception. It also improved the volume/loudness of the radio station. I couldn't believe it worked so well, so I am very pleased.

These tunable loop antennas are the most cost-effective way to improve AM radio reception in your home. Radio Shack used to sell a similar product, with the actual loop encased in black plastic, but those items haven't been available for years. It's good to find that someone else is still making them. In most circumstances is isn't even necessary to attach this antenna to the radio; just bringing it within a few feet of the radio is effective. You simple tune in the station on the radio, bring the antenna close, and fine-tune with the knob on the antenna base. If you have a console stereo receiver, or are trying to pull in a particularly weak station, you can connect this antenna directly to the antenna terminals on your receiver, with the included cable. If you can hear the station at all, this antenna will improve reception. To make sure you know what you are buying, note that these antennas work for AM signals only; they will not enhance FM or reception on other radio bands. Overall, good product: simple in concept, solidly built, effective in function, and reasonably priced.

I’m using this on an antique radio which was designed to work with a long wire antenna but this loop is working perfectly. Major thanks to the other antique radio reviewers that had good results. This is strictly for the AM band 550khz to 1700khz. For SW I obviously need to clip on the long wire. Not a big deal. The problem with a long wire antenna is they pick up all the RFI in the house. With this you can position the unit to null out the noise and point to the signal source instead of picking up all the noise at 360 degrees. FYI, my old radios have an internal antenna transformer coil (no ferrite coil or internal loop). Since this is a tuned circuit it needs to be tuned to your radio’s tuner for each station. With surprisingly good selectivity too. I just bought two more for my other old radios. No more long wires all over the house and no more noise. Update 5/1/25: Great design but terrible quality. After very very very little usage the tuner starts making a scratching sound as if the tuning capacitor plates are shorting. Then, the tuning capacitors open up completely rendering the antennas useless. I’m speaking in plural because I purchased three and two are dead and one I haven’t used yet. I was able to find a replacement capacitor on Amazon which fit perfectly but it has a limited frequency range.

Not meant to give perfect reception but does definitely improve amplification of weak station reception

No es la más nítida calidad pero si funciona y de un 1 a 10 le doy un 9 la tenemos usando desde hace un par de meses y sigue haciendo su función, la recomiendo por su calidad precio

Works pretty much as advertised. It is not perfect but did improve my AM reception on a table top radio to a considerable degree.

The Kaito AN 100 AM antenna works very well. The small loop antenna which came with my Tivoli Audio (Music System) had difficulty picking up our favourite AM station (100 miles away). I took a chance and ordered the Kaito AN 100 tunable antenna. It lives up to it's promise and brings the station in loud and clear. I had to solder on a 3.5 mm stereo connector to the cable provided by the manufacturer since the Tivoli radio requires the e antenna to plug in.

Blown away how well this product works. You can see the signal diff in my pics. The performance of this was far better than the ccrane am amplifier.
