I did create, thanks to yours informations, my Pinwheel and Cloverleaf antennas and they do work unbelievable (only itch is: to be careful the way you land not to make a pancake out of it)Ö

My question: how important is the length of the feed point, should it change with frequency, does it change impedance, does it matter at all?

Second question: should the length of the lobes of the Cloverleaf (for a pairs of matching antennas) be longer than those of the Pinwheel?? (I have found contradictory opinions on the matter)


Yes, keep the feedpoint as short as possible and yes, the CL lobes should be about 2 - 3% longer than the lengt of the SPW.
