Is antenna a transducer to 377 ohms?

The page at: http://home.comcast.net/~kb7qhc/ante...pole/index.htm dramatically reveals that the near fields fluctuate wildly from 377 Ohms, and I have restricted my analysis to those values falling at roughly 100 Ohms or 1000 Ohms (the hot spots marking the feed point region and the tips of the dipole). Other antenna design's modification of the 377 near field around them can be observed at: http://home.comcast.net/~kb7qhc/ante...elds/index.htm 73's Richard Clark, KB7QHC |
