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 |

Hard to disagree, xince that's what I use! Without any coax the G5RV fits in there somewhere.

There seem to be many different antennae called G5RV. I wonder when the G5RV vertical will come out? ;^) - Mike KB3EIA - |

![]() My non-random length high-Z0 feedline is better, Reg, i.e., NO tuner losses. -- 73, Cecil http://www.qsl.net/w5dxp =========================== Cec, I'm very sorry to say your variable length high-Zo line never reduces SWR down to 1-to-1 as perceived by the transmitter. It's like having a tuner with only one knob on it. Of course, your particular PA may have a tuned tank or pi-match in which case you will have reduced the so-called SWR meter to nonsense for which you deserve congratulations. But if the long, thin, twin-wire feedline in your ingenious Z-matcher has a higher resistance than the shorter, fat, single wire wound around the tuner coil it replaces then you still have some explaining to do. On the other hand, considering the economic pro's and con's, and the poverty-stricken state of radio amateurs world wide, you undoubtably have a winner. ;o) --- Your's, Reg, G4FGQ |

You know I've been watching the posts in this group for over a year now and
no matter what anyone says you guys always have a negative to say about somebody elses antenna. So may you have a Happy Christmas. I have attached the writeup from "ol' G5RV himself that was posted on several websites. Here is the original article and I still believe that the antenna I described is very close if not in fact the same construction. http://www.qsl.net/aa3px/g5rv.htm Lloyd KD4HTW "Reg Edwards" wrote in message ...

It's like having a tuner with only one knob on it. 50 ohm SWR's on all HF bands are less than 1.6:1. The SWR on the ladder- line is always between 7.5:1 and 19:1 so only one "knob" is needed. -- 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! =----- |

My XYL took a look at that setup, and informed me that that was the lowest on her list of "allowables" ! 8^) - Mike KB3EIA - |
