Nice to see the reflector active again. I am contemplating a 4 square for 80 this year, not with 1/4 wl but 3/8 wl radiators and spaced at 1/4 wl . Their impedance is the same but the current maximum is higher from the ground which should help make the system more efficient (ground loss). Does anyone here have experience with this design ? 73�s Henrik OZ1ING
