J-pole question
You have a point Mark. I agree that a simple 1/4 wave groundplane is more
study and very easy to make using an so-239 and some piano wire. Steel wire can be soldered right into the back, four bolts with nuts and four more peaces of wire around 19" long with a bit of a downward bend and you have a very good antenna. It's worth noting that you don't actually need four radials. Two radials (on opposite sides of the feedpoint, bent down at around 45 degrees) will produce a perfectly satisfactory ground-plane. The patterns of 2- and 4-radial ground plane antennas are almost indistinguishable. A 4-radial antenna may *look* as if it would produce a much more circular pattern than a 2-radial antenna, but this doesn't turn out to actually be the case. -- Dave Platt AE6EO Friends of 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! |

J-pole question
"Wayne" wrote in message ... "Kevin" wrote in message ... At least it's good to see that my posts are making it out! The French, in the cities tend to be rude and arrogant -- kind of like New York City but worse. In the smaller towns they are quite pleasant and welcome tourists as long as they don't act like "rude Americans" and expect "special treatment." - I personally had terrific interactions with people in France. However, it is still a lot of fun to have jokes at their expense My only time to be arrested in 68 years: Paris, early afternoon, public park, sober, in USN uniform. Have all the fun you want with jokes at their expense. Eskimos have over 60 words for "ice." The French have about that many for "surrender." OK, I'm done. |

According to Hank (the cow dog) chickens have about 12 words. All of them mean "HELP!" |

A 4-radial antenna may *look* as if it would produce a much more circular pattern than a 2-radial antenna, but this doesn't turn out to actually be the case. That's true as far as the pattern. But.. The more radials you use, the better the decoupling from the feed line. Most of my 1/4 wave GP's actually use 6-8 radials. I've done tests, and it does make a difference. But for casual use, what you say is true. Only two radials are required to get a pretty good omni pattern. Or one, if vertical.. But then you might as well call it a 1/2 wave vertical instead of a ground plane. And you will then require some kind of decoupling scheme below the vertical for optimum results. I prefer radial sets, cones, etc vs feed line chokes. |

In the smaller towns they are quite pleasant and welcome tourists as long as they don't act like "rude Americans" and expect "special treatment." I've found that when I attempt to speak the language, I'm pretty well treated. Now there is the possibility that they just find it amusing and charming, because I took both French and Spanish, and in conversation I can slip between both languages inadvertently. Usually when I note that I "Parlez poco Francaise" they start smiling.... As for New York, I haven't had much trouble there, but then I give back what I get. Most seem to actually like some attitude. Go figure! Like the old joke "Can you tell me the directions to Soho, or should I just go @*^! myself? Whaddevuh! 8^) - 73 de Mike N3LI - |

Do you know why there are so many trees on the streets of Paris? To give the Germans shade while they are marching. |

Ahh, the brothership of Hams - Good to see a friendly face here Kevin. - Mike N3LI - It was a lot like that in Germany in the 80's .I was stationed there for 3 years and found if you get out of the "GI Towns" and went to the smaller villages and towns outside of the bases they treated you like gold.Of course I guess that's like anywhere else you get out of the big cities and people are a more laid back . |
