It's not mounted in the best of places, due to the need for me to be somewhat stealthy at my condo. I also run only QRP power levels, mainly to mitigate the risk of interference complaints among the neighbors, and have managed to make more than my share of contacts using 5w on phone from 20 to 10 meters during contests like the recent ARRL Sweepstakes. Hopefully conditions (and available operating time) will be good for 10m this month for the ARRL 10m Contest. -- -- //Steve// Steve Silverwood, KB6OJS Fountain Valley, CA Email: |
Steve,
If yu can handle a full sized one 102' and you'll be very happy. Now you can build it yourself OR you can buy one from various vendors. Me I decided to "stay as true to G5RV's article" and bought a G5RV from W7FG.com as it is tru ladder line and actually is only two wires from the PL259 connector to the end. simple and it works. http://www.w7fg.com/ant.htm G5RV 80 - 10 Meters (102 Feet) With 31 feet of Ladder Line.........................$35 Requires Coax from supplied UHF Male connector to equipment.

Hi! G5RV 80 - 10 Meters (102 Feet) With 31 feet of Ladder Line.........................$35 Requires Coax from supplied UHF Male connector to equipment. and symmetrical ATU ..........................$??? |
The G5RV works better by removing all the coax and taking open-wire line of
any convenient length all the way back to the shack. Dipole length can be increased by as much as 40 feet with benefit. |

Mike sed,
Not much of a G5RV then is it, Reg? ----------------------- Exactly ! For all-round, multi-directional, multi-elevation, multi-band working, DX and local, there is nothing better than a random length dipole with a random-length high-Zo feedline, which is what most people want and which will conveniently fit into your backyard, plus a simple home-made 1:1 choke balun on a ferrite ring from your junk box, plus a tuner of some sort. Without any coax the G5RV fits in there somewhere. A sentiment with which that grand old English gentleman himself, Louis Varney, would whole-heartedly agree. Are you hearing me Louis wherever you are? Three dots for Yes. ---- Reg, G4FGQ |

Cecil, I have experience on the bands on 20 thru 10, but less than a couple of dozen chats on the other bands in as many years. Yesterday I scanned 80 and heard a spanish station but the East coast were piling on him. The point I am mentioning it is that my antenna is also horisontal polarised on the top of the tower. So I went to top band and scanned it for DX but heard NONE even tho the band was busy. I decided to key up and had a few contacts at around 1000 miles and with less with 30 watts and got very good reports. Is this about normal for your G5RV which is also horizontally polarised?

So I studied it to find out what was wrong. It was designed before the WARC bands and works well on 80m, 40m, and 20m. At the height of the sunspot cycle, you can work the world on 10m with a coat hanger and ten watts so the losses on 10m may not be important. But EZNEC says the SWR on 10m is about 50-60:1. I don't use a G5RV any more but I remember most of the data I collected. Why it works well on 80m and 40m is illustrated on my web page. -- 73, Cecil http://www.qsl.net/w5dxp -----= 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! =----- |

Go figure... At the higher frequencies, small variations in design and environment can cause large shifts in characteristics due to the shorter wavelengths involved. For instance, if the dipole is a little longer than 102 ft, the series-section transformer is a little longer than 30 ft with a relatively low VF, the G5RV antenna system's resonant point will shift a lot on the higher bands. Also, installing the G5RV in an inverted-V configuration can change things considerably on the higher bands. I'm glad it works well for you on 17m. That's a neat band. -- 73, Cecil http://www.qsl.net/w5dxp -----= 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! =----- |

Dear Rich,
Your summing up of 20th century middle eastern warfare and the decay of the British Empire, on which the Sun never Sat but now has, is reasonably accurate. Thanks for your careful trouble. Between you and us, the aggressive character of the English-speaking and European peoples has resulted in the present worse-than-ever mess - Armagedon is at last upon us. In previous centuries, before the internal combustion engine had been invented, so-called civilisation, originating in Ur, Babylon and along the Nile, had extended westwards as far as northern Spain and Vienna in central Europe. The weapons of mass destruction then were, in their time, Greek Fire, gunpowder, and biological weapons such as catapults to fling plague-diseased corpses over the walls of beseiged cities. The Inquisition has it's modern counterparts. (The chemists of an independently originating civilisation in Eastern Asia had invented the chemically propelled sky-rocket but the peoples of that great land, having genes of a less aggressive nature, preferred to use it for pretty firework celebrations. Incidentally, Chinese metallurists had invented cast iron, 1000 years before the industrial revolution began in Europe in the small town of Ironbridge, in a gorge on the river Severn, just a few miles up the road from my QTH.) All human decisions are made on the basis of what is already known. What is already known is History. History should be the most important subject taught in our educational institutions. At present, alongside geography, it is the most neglected. All we have are newspaper hacks, TV news-analysts, and the monitored dis-information Internet. Some names in history - Attilla the Hun. Emperor Nero. Ghengis Khan. Napoleon Bonapart (Not tonight Josephine) Adolph Hitler. Joseph Little Uncle Stalin. "Enora Gay" George Self-confessed Crusader Bush. ---- You can add me if you like - Reg G4FGQ Edwards. -- .................................................. ..........

What's all this got to do with the subject, ' G5RV'?
Seems it's a bit off..... |
Dear Jacques,
Oh yes, I was perfectly aware Bonaparte was the odd man out. I put him there to suggest to a minority of USA readers the possibility that a similar sort of error might have occurred with George B. ---- Reg, G4FGQ ============================= Reg, If you place Napoléon Bonaparte beside Hitler and Stalin, I am not sure you know something about history. Of course you may consider metric system as another plague ;-)) 73 de Jacques - ON5MJ |
Jacques wrote,
Thank you Richard for defending His genius. I am living 15 km from the battle field of Waterloo and what is funny is that we celebrate Napoléon, not Wellington. The duke of Wellington was the winner but is rather forgotten. His museum there is as big as a coffee shop while Napoléon is displayed everywhere. Maybe because we never forgot that we were french before 1815. Now there is a lion in bronze made of gun-metal on a 45m hill at this place (but nobody is allowed to attach a G5RV on the top, ... on day I will try to find the frequency of resonance of the lion itself). The only thing I would like to add is that we are to-day (december 20th) the 200th anniversary of the sale of the french Louisina by Napoléon to the United States of America. USA added 12 states and increased their surface by a factor of 2 in one hit of magic wand. It was the first step of the westward expansion. The price was not that high as USA paid only 400 million dollars (of to-day). Napoléon estimated he couldn't afford to maintain troops there and to administrate the country. So he decided to sell this area to Americans by friendship instead of being forced to give it for free to UK. This permitted to Americans not being surrounded by British troops. Have a nice Christmas. 73 de Jacques - ON5MJ Wellington didn't win that battle, Blücher did. According to Victor Hugo, Wellington even had the gall to criticize the quality of his own troops afterward. 73, Tom Donaly, KA6RUH |
Jacques wrote;
Thanks Tom for this precision. But Blücher has no museum at all in Waterloo. The only one on the side of the winners, is the one of Wellington. I didn't know that Wellington criticized his own troops. Victor Hugo was probably the greatest french writer but he was very much Napoléon minded, so ... ".("Waterloo, morne plaine"). He even called many years later Napoléon III, "Napoléon-le-petit". Also, sometimes schools are not honnest. Blücher was prussian and after WW2, when I was at elementary school, it was not well accepted to dress germans with the clothes of winners. And I was a bit confused also by the fact that since 1815, Belgium pays a fee to the family of Wellington (I know it's very few now because the value of money has dropped but it still exists because there was a signature on a piece of paper). I sincerely thought that he was the winner, because he administrated France from 1815 to 1818 during the occupation period. 73 de Jacques - ON5MJ Blücher arrives in the nick of time and Wellington gets the credit. Oh well, life isn't fair. Scientists, mathematicians and others sometimes get shorted by history because the historians are confused. Some contributors to this newsgroup like to complain about Heaviside's treatment by the historians. Just write something about "Maxwell's equations" some time and watch what happens. 73, Tom Donaly, KA6RUH |

"USA added 12 states and increased their size by a factor of 2 in one hit of magic wand." The Louisiana Purchase from France was the most important item in the territorial growth of the USA. Jefferson wasn`t sure that it was even legal according to the US constitution when he bought the territory, but he was sure that it was necessary, so he did it anyway. Thomas Jefferson succeeded Benjamin Franklin as minister to France in 1785. Jefferson sympathized with the French Revolution. Jefferson was a reluctant candidate for President in 1796, and became Vice-President in the Adams administration as runner-up due to the election law at the time. In 1800, Jefferson was elected President. He sent the U.S. Navy to the Mediterranean to dispose of the Barbary pirates who were harrassing American commerce. I think the term "To the shores of Tripoli" in the Marine Hymn comes from that action. As the Marines say, "when it absolutely has to be done, the Marines are ready." Jefferson acquired the Louisana Territory from Napoleon in 1803. He sent Lewis & Clark in 1804-1806 overland to Oregon to examine the purchase and claim it for the U.S.A.. The explorers did a magnificent job. During Jefferson`s second Presidential Term, he devoted much of his energy to keeping the U.S.A. clear of the Napoleonic Wars, though both England and France interfered with the neutral rights of American merchant ships. The Louisiana Purchase was essential in creation of a powerful nation spreading from the Atlantic to the Pacific. Jefferson, the purchaser, died at 83 years of age on July 4, 1826, anniversary of the Declaration of Independance of 1776 which Jefferson mostly wrote. He usually was the brightest bulb on the tree.
