Here is my 'opinion' based on my personal experience using the Sony ICF-SW7600GR 'portable' AM/FM Shortwave Radios by itself; with a 23 Foot Roll-Up / Reel-Up "Portable" Shortwave Antenna; and the Sony AN-LP1 Active Shortwave Loop Antenna 1. The Sony AN-LP1 Active Shortwave Loop Antenna is "Tunable" (Pre-Selector) and can easily be place in a location (window) for the 'best reception' = Strongest Signals and Lowest Noise. 2. The Sony AN-LP1 Active Shortwave Loop Antenna works well for a Traveler who only has a Hotel/Motel Window as their "Gateway" to the World of Shortwave Radio. 3. The Sony AN-LP1 Active Shortwave Loop Antenna can also work well for some Shortwave Listener's who live in Apartments and Condos and are very limited in using any type of OutSide {Random Wire} Shortwave Antennas. 4. Most of the time those little 23 Foot Roll-Up / Reel-Up "Portable" Shortwave Antennas that come with many 'portable' AM/FM Shortwave Radios do not perform as well as the Sony AN-LP1 Active Shortwave Loop Antenna. This is whether you Plug the Sony AN-LP1 Active Shortwave Loop Antenna into the Radio's External Antenna 1/8" Jack or simply Clip-It-On to the Radio's Whip Antenna. 5. For Shortwave Listening (SWL) the combination of the Sony AN-LP1 Active Shortwave Loop Antenna and the Sony ICF-SW7600GR Radio usually works better then using the Radio by itself. TBL - Yes the Sony AN-LP1 Active Shortwave Loop Antenna does amplify the Noise along with the Signal. But when you can not Hear them : Then something is better then nothing. Not a perfect solution but simply better than most other available or permitted options. You could very well be correct. This may in-fact be THE one portable amplified antenna that is able to deliver signals that could not be gotten with either the whip antenna or a simple wire antenna strung around a window. My experience with many other wunder-antennas has been that they are little more than a gadgety external volume control. After turning one or more knobs all signals get equally louder, but nothing magically pops out of the mud. I've taken a variety of (mostly Sony) shortwave portables on trips over the years and have found that a simple wire strung around the hotel room window will gather a lot of signals in a less then perfect listening environment. I may be wrong....and if I find one cheap enough I just might try it. But not at the going prices. |

www.devilfinder.com Build your own amplified radio antenna and null
out unwanted noise Seems to me in this modern technology age,there should be a way to build a very good amplified antenna without the unwanted noise.How do amplified antennas work anyway,do they boost the radio signals? cuhulin |
