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. That proves that no antenna is perfect for everyone. 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 What he left out is the SWR on the coax which is a killer on 30m, 17m, and 10m according to EZNEC. -- 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! =----- |

Oddly enough, the full sized one I have, in addition to OK performance
on 80/75, 40 and 20 works better than anything else I've tried on 17. It really does do poorly on 30,15,12 and 10 though. Go figure... |

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! =----- |
