Not all the old timers disagree with me, so I am betting this is a pretty common problem when discussing antennas. What you have is a *physically* short antenna that is *electrically* Does this mean that I can call a 5/8 antenna a 3/4? I would think it should be one way or the other. I was really hoping for a more definative answer than I have gotten here so far as there is a signiificant quantity of beer at stake. I know what I have I just want someone to settle the argument on what it should be called. In other words, should we use physical length or electrical length to describe an antenna. It is my opinion that antennas should be referenced by there physical length otherwise we will be giving creedance to those who are trying to sell 5/8wl antennas that are physically only an 1/8wl long. 1/4WL long. This usually involves a loading coil. Also, the electrical length of a piece of coax is longer than it's physical length because of the velocity factor less than 1.0. -- 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! =----- |
