Review on Kaito AN-100: Tunable Loop Antenna for AM Radios- Compatible with Kaito, Sony, Panasonic, Grundig, and More by Jesse Francilme

I'm sure the people who returned this product just didn't use it properly or were impatient. If you have a radio like the GE Superradio, some of the Grundigs or other high end radios that already have great ferrite antennas, 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've tested this loop with all my radios and I have a lot of them. This unit does a great job of finding and dropping stations during the day, even if it's a strong station for you, if you tune in slowly and find a sweet spot, if nearby stations go to zero, hiss, etc. If you have a radio with you one of those cheap loops that plug into the jacks on the back of the radio, put that crappy loop in that kaito loop and tune slowly. You will be amazed at what he can do for you. I also enjoy nighttime DXing with this loop. I use either my Sangean ATS-909 or a Meloson DSP multiband radio. What a wonderful, simple addition to listening to the radio. Adds a lot to my enjoyment of DX radio. First you need to find the spot on your radio where the ferrite antenna is located by slowly moving the loop along the front or back of the radio. This works by induction. The loop doesn't actually have to touch your radio, just bring it closer. You can tell whether you are in the right place by the sound quality of the station. It will either make him stronger or weaker. Then slowly use the tuning knob on the loop to find the sweet spot. On my radios, the 850 is right in the center of the tuning knob on the loop. At night I can reset nearby stations, it REALLY helps. This is a great product. People just need to be a little patient and lightly touch the tuning button on the loop. Thank you Kaito!
