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. |

Thanks for the comparison link,. I've been waiting for this and maybe a few
more antenna comparisons as well. 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 ...

Found!
http://www.universal-radio.com/catalog/sw_ant/2205.html Par Electronics EF-SWL Do you or some of the others have any input on this antenna? Seems a bit too good to be true but great if it works.

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 |

Par Electronics EF-SWL
"Cheaper just to roll your own transformer and hook up a wire to it." I have a 9::1 balun. This coax cable they describe, would any other cable say RG8/RG6 do the same job? Live close to heavy industry and the noise at times just blankets the area. NEED a quiet antenna. Thanks for the help! R71A, NRD-535, NRD-525, E1 Main receivers. "dxAce" wrote in message ...

Thanks for the help! -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- If you need a "quiet" antenna, go for a loop. I had a home brew loop that worked well, though I had to use a preselector with it. It was almost like a miracle. Because it was a shielded loop, there was almost 50dB less noise, and good directionality. I made the thing from 5/8 copper tubing and some 8 AWG electrical cable. I just put the cable inside the copper tubing, then connected the three wires in series, soldered one end to the tubing and connected the other end to the center of a piece of RG-8 (RG-8X is just as good and much easier to handle) and clamped the ground braid to same place as the wire attached to the tubing. This was a 4' loop, so worked as well at MW as SW. Unfortunately, I don't have it anymore because the harsh climate destroyed it after only a couple years. |

This I'll try. 'Doesn't matter about spacing at the loop ends just as long
as they're not touching, 1 or 2 inches? I have a rotor that I bought at a Radio Shack clearance for a project like this. This should help a bit with reception as well. I heard of someone using a hula hoop for something like this but copper tubing I guess makes it a magnetic loop, which I hear is best for a low noise antenna? Still use the balun? A thousand thanks for the instructions. "Brenda Ann" wrote in message ... "Justis" wrote in message ... Par Electronics EF-SWL "Cheaper just to roll your own transformer and hook up a wire to it."

One last thing, I have some 3/4" copper tubing available to make a 4 foot
loop. Will this work and roughly how much cable should I stuff inside, fill 'er up? "Justis" wrote in message ... This I'll try.
