Hi Gang,

I should remember this but I am putting this theory question out to the group.  What is the minimum altitude when an antenna stops reacting or interacting with ground?  Is it a half wavelength or a full wavelength?  Naturally for the purposes of this discussion I am leaving out ground mounted verticals.  It has been a while since I visited this segment of antenna theory.  Any info is appreciated.
