hey bob , that is from your first post starting this thread .

this line in particular caught my attention .


"Length ratios in excess of 3.2:1 produce higher level sidelobes and less gain on the horizon, except for

narrow spots near the even ratios of 4:1, 6:1, 8:1, etc. These are where the central monopole is an even

multiple of a halfwave, and the antenna mode impedance is too high to allow much antenna mode current"


any thoughts on what might be expected from this style antenna with a full wavelength center driver ?
