That will give a good idea of the pattern, but not for finding the gain
relative to a dipole. I suppose I could set up a dipole and compare the
readings, though... a little difficult for me to read my current J-pole,
though, because it's up on the roof and I can't get to it. :-{

Ok, let's try these, (part of my HAM tagfile...) Enjoy!
