To those that said it would not work
Remember back when some said my Open Stub J-pole (OSJ) design
Would not work very well. Just take a look at 25 reviews at A HREF="http://www.eham.net/reviews/detail/1613"eHam.net Reviews - OSJ Model J146/440/A or http://www.eham.net/reviews/detail/1613 See if you can find the ONE review that did not give it a 5 out of 5 rating.

I have built 5 of these antennas for myself, family and friends based on
your webite description and all of them work wonderful. One of my club Members even ran it thru ez nec and it looked great there too. Thanks. John, VE2JDR "Arrow146" wrote in message ...

Hello,
It's always funny to see people saying, "best I have ever used" etc, what must they have used before! It's not really a new design is it, maybe just similar to what is known as a "nest of dipoles" that scanner enthusiasts have. They use different radiating elements in parallel.

Hi Jason, Not that at all, otherwise all of the elements would be driven, and simple observation negates that. I've reported a similar design to this group years ago that uses the SO-239 bulkhead connector wired up in similar fashion: One wire extending directly from the center pin solder tail, and another wire, parallel, soldered to any of the four holes normally used for mounting. No need whatever for the usual JPole tuning cap. 73's Richard Clark, KB7QHC |

No need whatever for the usual JPole tuning cap. There's an analysis of a similar design on Cebik's web site - his "non-standard J-pole" is a bottom-fed, non-shorted design with a shorter-than-usual radiating section and a longer-than-usual matching leg. http://www.cebik.com/jp1.html It looks to me as if the Arrow design has similar element lengths to the one which Cebik models. The Arrow trick of using one element as the matching leg for 2-meter and as the radiator for 440 is a slick one. Everyone I've spoken with who has used an Arrow 146/440 J-pole has been very happy with it. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

Got one in my junk bin made of coathangers and N connector for two meters It worked so much better than my rubber duckie antenna I thought it was the greatest antena in the world.. |

ANYTHING will work!
The question arises how WELL will it work? Without quantification, statements are meaningless. Specially when the weakest parameters are not mentioned in specifications and are not discussed amongst the biassed-in-favour so-called judges. |
