Hi Simple answer is that the “simple” approaches don’t do much to improve things. Errors are indeed un-correlated, even off of the same antenna. You *could* average the result off of the two. That might improve things by sqrt(2). My experience is that the bumps and lumps (when they do occur) are not the sort of thing that averages out nicely…..
