Hi ShortwaveMan,
Sorry for the delayed reply; I don't go on the internet everyday. The loop is made of aluminum and is about 3-feet in diameter. The antenna interface and power supply is located somewhere conveniently near your receiver. You can see pictures of the unit on the website. The antenna does not feature exceptional gain; that is not its design goal. What it DOES do (and EXTREMELY well) is to lower atmospheric and local electrical noise relative to the signal. In other words, this antenna greatly augments the signal-to-noise ratio of the short wave signal. If it is there, you will be able to hear it. If one is in an electrically quiet area, a long wire will do as well or better in the winter, though not necessarily in the summer. However, in your circumstances, it may be your best choice. Of course, we have to be practical in today's world and there is no denying that it is a costly piece of equipment (though you only have to buy it once; you will probably change radios many times if you stay in this hobby long enough). Check it out. (That costs you nothing!) Best, Joe ShortwaveMan wrote: Thanks Joe. Can you give me any idea of how it is constructed ? The US West Coast does not enjoy as good reception as other areas of the world s, so it is a bit of a challenge. Thanks again. "Joe Analssandrini" wrote in message oups.com... Dear ShortwaveMan, I don't know what your apartment is like or what you are prepared to do, but I had a similar problem. As a matter of fact, last year I was quite desperate. I live in a small townhouse and the community is a source of EXTREME local electrical noise, what with Christmas lights, computers, often-defective LP Sodium and Mercury Arc-vapor street lights, and high-tension lines not a quarter mile away. You can imagine what all of the above did to my SW listening. I won't go into the various "fixes" I tried over the years (they have been "posted" on this site and elsewhere), but I FINALLY found the one! It is the Wellbrook ALA 330S Active Loop Antenna. You can investigate it he http://www.wellbrook.uk.com/ Note it is quite expensive (probably around $400 now, due to the poor dollar-to-pound ratio), somewhat convoluted to buy (I bought mine from THE SHORTWAVE SHOP in the UK, the only dealer which sells it. They accept credit cards. You can buy from the factory, but only with a check), and it's BIG - the loop is about 3-feet in diameter. I have mine mounted in my attic, but mounting is not critical. It COULD be mounted in your room (near a window) if your significant other is broad-minded, outside mounted on a deck, if you have one, or some other "creative" place, This antenna is positively FANTASTIC. It dramatically lowers both atmospheric AND local electrical noise. In other words, it greatly increases the signal-to-noise ratio of the signal you are trying to hear. An example: I live on the East Coast of the US, yet I have been able to regularly hear Radio Australia's 2200 - 2400 UTC broadcast on 21740 kHz. The signal comes in at only S4 - S7, but is perfectly clear and fully listenable. At the very least, look it up on the web. I completely sympathize with your problem and I hope you are able to come up with a satisfactory solution. Best, Joe |
