i stated from day 1 over 10 years ago that the 4 radial vector shortend  outperforms the 3 radial avanti and the old style vector eddie, not that i don't see anything with the avanti,


i have said a dozen or more times what the problem is with your testing,

im not saying my way is perfect far from it but we eliminate as best we can 4 variables you include in your tests,


eddie,

how does your one set of currents jive with this ?


in the open sleeve antenna as you bring the sleeve element spacing closer to the monopole the input impedance of the antenna drops and current increases,


what causes that eddie?


it is claimed that sleeve spacing has little effect on Za ( monopole antenna mode impedance ) so we can't blame the sleeve for causing a drop in Za as been the cause of the lower impedance and increased current,


you have not changed the physical length of the monopole or radials to change Za,


it is claimed that Za may even rise a little as sleeve spacing decreases


why do we see impedance drop and current increase eddie ?
