Thanks for describing this antenna in an easy to understand fashion.

There was one advertised recently and I remember it was a piece of coax that you could lay around the apartment and it supposedly gave you remarkable results for around $75 plus shipping CONUS. I've done a search of cable antennas but cannot find it now. Perhaps you or someone can remember this. Anyway thanks for your time. "Steve" wrote in message ... For the diminishing number of you who are still interested, here's a link to a review comparing one of the Wellbrook loops to Pixel Technology's RF Pro-1A magnetic loop antenna: http://www.wellbrook.uk.com/reviews/...O-1AReview.pdf I still prefer a tuned, passive loop to the amplified, broadband variety. The PAR EF-SWL is actually a random wire with a very well made matching transformer. It is likely to be a very good antenna of its type. The antenna "radiator" is not a coax, but a plain insulated flex-weave wire, designed ideally to be suspended at some height above the ground. If installed properly, it should provide a good signal to noise ratio. The Wellbrooks are somewhat more elaborate designs, amplified magnetic loops. They work very well in RF-noisy places, but you pay for compactness and performance. Bruce Jensen |

Thanks RHF, looks like I just might be able to tame some of the noise after
all. I know it's best to have a good receiver and that it's only half the battle. Not much good without a "good" quiet antenna as well. I was getting pretty discouraged trying to listen to weak stations with all the man-made noise in the area. I think this group may have set me on the right path for more quality listening. Thanks for sharing your expertise. "RHF" wrote in message ... On Feb 5, 12:48 pm, "Justis" wrote: Par Electronics EF-SWL "Cheaper just to roll your own transformer and hook up a wire to it."
