Pseudo experts of fractional wavelength antennas. Where does the current flow when it reaches the END of a fractional length? verticle antenna and why? How does this relate to the term "end effect"? If you have already written a book then tell us what the auther said. Art KB9MZ.....XG it turns around and goes right back down the way it came. So a electrical generater doesn't keep turning in one direction but instead it occillates at the desired frequency. I have never seen one do that! And "end effect" is the confusion created at the top of the radiator 'end effect' is an effect of the capacitance seen from the end of the antenna to ground or the other part of a dipole. how does a generator come into this? you feed current into a wire with an open end, it gets to the end, reverses direction and goes back to where it started. no frequency was stated or implied all you asked was where there 'current' went... that could be any kind of current including a step or pulse or sinusoids of any frequency.- Hide quoted text - - Show quoted text - The current comes from a generator does it not? So how is that current produced? I see a generator turning in one direction only all the time where you are suggesting that it is occillating. Pretty hard to draw a circuit if it tracks back the way it came. Draw a graph of an occillating current as you would see on a scope that shows two degrees of freedom. Does the "x" direction stop after a half cycle? i don't need a generator to create a current. hook a battery to a piece of wire, watch the current travel to the end of the wire then reflect back. its easy to do the measurements and they match exactly the theory. i use this all the time, its called a time domain reflectometer. very handy for finding breaks or bad spots in feed lines or Beverage antennas. use one for a while and you will become much more familiar with the true effect of currents on wires and reflections. |
