Was pondering this while out walking the other day, and couldn't come to a satisfactory conclusion either way... A small magnetic loop mounted vertically has a defined radiation resistance that is a
Andy, Better yet, take a soccer ball and start winding wire around it until you have completed a 90 degree arc on both sides. What's the resulting pattern? John Andrews, W1TAG
Dear Andy, I guess these two loops should be fed by two rf signals of 90 degrees phase difference to become really omnidirectional. The same is true in receiving. The two signals from the loops have
Gosh are you guys getting civilised at last, to recognise a spherical football <g> Ok course one would have make corrections for the "Beckham Effect" ! Alan G3NYK
A small magnetic loop mounted vertically has a defined radiation resistance that is a function of its diameter, a loss that is function of its conductor and hence a loss or efficiency that is the rat
Tnx for the replies on this. In the original post I'd forgotton that Chu-Harrington described a sphere just sufficient to enclose the antenna, so a pair od crossed loops would fit into the same size
I think, Alan, that to achieve the "Beckham" effect would require that you arrange for the resulting radiation pattern to achieve a "curve" in the general direction of the beam pattern and it will pr

you have completed a 90 degree arc on both sides. What's the resulting pattern? I'd guess the sum of all the individual loops, which should be in their average direction, i.e. with the flux coming o
