Hi Richard, Then that is dashed by his having trimmed the ends (presumably everything at the same height, and as such in a direction away from earth) and the multiplier shrank more. More likely the capacitance between the ends grew instead (corresponds to all factors observed). 73's Richard Clark, KB7QHC Now THAT makes sense! I was worried that at the rate I observed the nnn/f formula decline, your average 10m dipole would be stupidly short! And, for the record, I never touched the height of the feedpoint or the angle of the legs. Instead of tying to the tips of the legs, I attached the guy lines (heavy duty natural twine) about 8" up from the ends. That way, I could trim the ends without having to redo the supports. I wrapped the twine around the ends to keep everything straight. So, only 2 things changed - the height of the ends (10') and the length of the legs. Thanks everyone for the ideas..... Ken KG0WX |
