Hiya...
One of my two antennas is a home brew 200 ft random wire antenna. It's well grounded and also makes use of a coax feed and an ICE-180 matching transformer. Most importantly, it's set up and folded more like a piece of modern art rather then an antenna :-). I've had a number of DX'ing friends over here to check out my R-75 rig and my antennas. A number of times, we have also had them bring their rigs over here, including an R-8A and a Kenwood R-5000. We did some side by side comparisons between radios to see what was the best DX'ing rig. Although we didn't come up with a definitive answer about what rig was best, we've decided that for reasons unknown, my 200ft "FRANKENSTEIN" random wire antenna was by far the best DX'in antenna that any of us have used. Still, I have no idea of what the thing is. I just strung the thing up.. LOL. Here is a link to the part on my DX'ing page that has comprehensive info on "FRANKENSTEIN" including diagrams. http://md_dxing.tripod.com/hobbyandhowto/id5.html Does anyone know what the heck this thing is ??? How would you classify this antenna besides being a work of modern art ??? LOL. There has got to be a reason behind it's performance. Any input would be appreciate. In short.. What the heck is it ??? -- Respectfully, Michael Home Page: http://md_dxing.tripod.com/ Northern NJ R75 w/DSP, Kiwa agc/sync & audio mods G5RV & 200ft longwire w/ICE-180 MFJ-1048 preselector SoundBlstr Live PC card w/five piece Cambridge speakers & full software mixer/eq. |

recent scientific investigations have found antennas based on a "fractal"
like pattern are better than their more conventional counterparts, but as far as I know, they have not come up with a reason s. |

That sorta resembles an inverted V folded dipole. At 200 feet, I'd bet it is
somewhat directional as well. Good looking design ! I did something similar once, but had a 20' wooden pole and did it similarly, and it worked well also. Is it just one long continuous wire, or two equally long halves ? |

You sure it wasn't meant to be a patio cover. The web page is really nice. Rob Mills ~~~ Tulsa, Ok |

Hi Michael:
I've found, that if you put up "More Wire" you get " More Signal". A John Carr book says if you Quadruple the antenna length to get a 6 DB ( Noteceable) change in signal strength. Found that to be true, - So it sounds like what you 've got ( 200 foot multi directional ) works pretty good ! - If you're bored, ( & hanker to terrify the neighbors, ) You COULD try ( using a different color wire to keep it straight ) put up another 600 feet of wire on your roof & see if it measurably increases signal strength..! I mean, if bigger ain't better, how do you account for Ariciebo or the Very Large Arrays, or Art Bells Huge Loop antenna? Antennas are a nice, cheap hobby . . ..

Hiya...
It's one long continuous wire... -- Respectfully, Michael Home Page: http://md_dxing.tripod.com/ Northern NJ R75 w/DSP, Kiwa agc/sync & audio mods G5RV & 200ft longwire w/ICE-180 MFJ-1048 preselector SoundBlstr Live PC card w/five piece Cambridge speakers & full software mixer/eq.

Michael:
- Maybe it's just a "BFA" class antenna. My Wife caught me up on our Apartment house roof, with a measuring tape and the Jwin JX -M14 -Just checkiing the circumference of the roof.. Antennas are totaly Verbotten. Promised her I wouldn't do anything until they actually install a lightning rod array up there. About once a year we get hit by lightning, totally fries the elevator controls. Does give one pause... Dan In article , "Michael" writes: There has got to be a reason behind it's performance.

Bigger is better providing your receiver can handle the greater signal levels without overloading. If not, you will be frustrated with all the spurious (false) signals to be found throughout the receiver's tuning range. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Most importantly, it's set up and folded more like a piece of modern art rather then an antenna :-). Where's the connection from the antenna to the matching transformer? I see the end of the wire connected to an insulator on the chimney but where's the other end (beginning) of the antenna wire that should be connected to the ICE-180? Also, if the antenna wire is a 200-ft continuous length, I don't see what path it takes to make the 'X' pattern. It looks like two seperate doubled wires crossing over the chimney top but not part of a continuous length of wire. It would be helpful if you added some arrows to show the path of the wire as you constructed it. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Michael,
Seems like you have already named your 200 Ft Random Wire Antenna. - - - So let it be "FRANKENSTEIN" ! - - - "Fran-Xan-Wire" would have been my choice ![]() Someone with Antenna Modeling Software may be able to give you a better 'idea' as to the reception pattern that your unique antenna exhibits. The Double Folded "X" Shape and the Ground Wire that bisects the field of "X" creates infinite possibilities. - - - http://md_dxing.tripod.com/hobbyandhowto/id5.html IMHO: What makes your "FRANKENSTEIN" Antenna such a performer is that fact that it uses the Low Noise Antenna design concepts a la "John Doty". - - - http://www.anarc.org/naswa/badx/ante...e_antenna.html - - - http://www.anarc.org/naswa/badx/ante..._longwire.html - - - http://www.hard-core-dx.com/nordicdx...eed/coax2.html Plus you used the ICE-180 Matching Transformer. - - - http://www.hard-core-dx.com/nordicdx...ed/ice180.html - - - http://www.hard-core-dx.com/nordicdx...d/magbal2.html Add-in the fact that your have a 'good' Grounding System. - - - http://www.anarc.org/naswa/badx/antennas/grounding.html - - - http://www.qsl.net/co8tw/grounding.htm iane ~ RHF .. .. = = = "Michael" = = = wrote in message . net...
