There is no discussion as to the genesis of this "approximation." There is no data garnered by experiment to support it. That's simply a false statement. So please tell us what objection do you have to the graphs in the ARRL Antenna Book (a previous reference of mine) from which everything I have said logically follows. I believe Tom's point was that more information was known or available preceding the "approximation" than following it, which portrays the "approximation" as a degradation of knowledge. That's a laugh since most hams are incapable of measuring anything like 3000+j2000 ohms. I have no idea what your (or Tom's) agenda is but it is apparently to convince everyone that shortcuts are useless and only gurus like yourself can bestow the sacred cow knowledge of antennas on us, the unwashed masses. -- 73, Cecil, W5DXP |

There is no data garnered by experiment to support it. That's simply a false statement. Recite your data. Once again: The ARRL Antenna Book, 15th edition, page 2-10, the graph of resistance Vs reactance in Fig. 10 for frequencies from f/2 to 2f. The same graph appears as a series of graphs in the ARRL Antenna Book CD, ver. 2.0. Everything I said falls out directly from those graphs. Fig. 10 is for a 1/4WL monopole so it has to be extrapolated for a 1/2WL dipole. The point of maximum reactance is approximately equal to the (anti)resonant resistance divided by 2. The resistance at the point of maximum reactance is approximately equal to the (anti) resonant resistance divided by 2. How can you guys get so upset at someone who simply describes a graph in the ARRL Antenna Book? -- 73, Cecil, 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! =----- |
