Niether of these hypotheses will go far to satisfy the real objectives of our study. Our focus has always been on real world performance differences for various configurations of mobile antennas, mast lengths, coil positions, multiple resonators, mounting angles, matching devices, magnetic mount effects, vehicle footprints, grounding methods, etc. think your position is clear….

Hello again, TomYou responded to my last post with some comments & question. Actually, the coil current measurements were made twice because the coil was always reversed to see if an anomaly was present in meter pickup. The objectives center on getting practical answers about practical antennas. BTW, the meters were read using binoculars.

He got us dozen small calibrated RF ammeters with very small thermocouples. When the whole study is published, there will be pictures of these devices included.
