![]() "Thierry" Thierry, see http://www.astrosurf.com/lombry/ wrote in message ... "Jerry" wrote in message .. . "Reg Edwards" wrote in message ... The moral is - DON'T USE A G5RV. Yup! I bought one in the late 80s and found that it was the craziest acting thing I had ever used! It most often drove my Yaesu tuner bonkers; other times it would settle down to an "acceptable" SWR. I fiddled with it for a summer, and finally threw it out. Hi, Sorry to say that but you experimented a bad experience. Who else has had non-success with this antenna? or have not enough knowledge to use it properly. Wanna BET? I've been doing this stuff since I was a child of 8--trying to get everything from a window screen to work to all sorts of wires and verticals. I learned from quite a few mistakes. Like wondering why I couldn't tune in those "Donald Duck" sounds (was SSB, but I was too young and new to know that). Or pretending that those heterodynes were airplane engines and I was a bomber pilot (drove my Mom crazy! and also led me to learn to fly! Just because something doesn't work for *me* does not make me an idiot. If it works for you, FINE! If it doesn't happen to work for me, that's fine, too. I didn't like the antenna, it made my Yaesu tuner go nuts, did things that couldn't be explained by usual antenna theory, and I shucked it. Jerry K4KWH I know several OM in ON that use G5RV, W3DZZ and alike, and even longwire of about 20-30m that have similar results than mine. And if the G5RV is always sold (thare a dozen variantes, see my website) after decades, there is a good reason : this is because it works well ! Never hear on bands OM working with dipole and G5RV ? There are a lot ! better, G5RV offer you the best quality/price ratio ! 73's Thierry ON4SKY I then made me a 75 M doublet fed with ladder line. .......it's still up there. Jerry K4KWH Specially one with any coax in the feedline. If you've bought one, you've been robbed. Use a random length dipole, longer than about 1/3 of the wavelength at the lowest frequency of interest. Choose a length which makes best use of the size of your backyard. Take the 450 or 600-ohm balanced line all the way back to the shack. You will need a tuner and a choke balun at the tuner. For multi-band operation you will need a tuner whatever you do. If you find it inconvenient to feed the dipole in the middle, and you have a relatively low local noise level, then feed it at one end and make an Inverted-L of it. It will then very likely work very well also on 160 metres. And you will never think of using a G5RV again ! By the way - Louis Varney, G5RV, a real genuine English gentleman, now no longer with us, designed his antenna to work most efficiently ONLY on 14.15 MHz, perhaps the best day-or-night, all-year-round, any part of the sun-spot cycle, DX frequency. It's very good. And you may not need tuner even with the coax. Works great with the old fashioned TS-520 with its built-in tuner ! ---- Reg, G4FGQ |
